TOPOLOGY AND CIRCUIT DESCRIPTION
This evaluation board features the ADP1043A in a typical DC/DC switching power supply in a full bridge topology with
synchronous rectification. Figure 1 gives a block diagram of the main components on the board. The circuit is designed to
provide a rated load of 12V/8A from an input voltage source of 36 to 60VDC. The ADP1043A provides functions such as the
output voltage regulation, over current protection, load current sharing with multiple power supplies over the share bus, over
temperature protection, and power supply shutdown.
Please refer to the appendix for the detailed schematic. The primary side consists of the input terminals, full bridge switches
(QA to QD), the current sense transformer (T4) and the main transformer (T2). The ADP1043A (U1, on daughter card) resides
on the secondary side and is powered via the USB 5V via an ADP3303 LDO (U2, on daughter card) present on the same
daughter card. The gate signal for the primary switches comes from the ADP1043A through the iCouplers ADuM5230 (U14,
U16) that provide isolation and power. The output of the iCoupler is connected to a buffer as it can source only 10mA of
current. This buffer (network consisting of Q5 and Q6, Q7 and Q8, Q9 and Q10, Q11 and Q12) is used to drive the full bridge
switches.
The secondary side power stage consists of the synchronous rectifiers (Q2 and Q3) and their respective drivers ADP3624
(U1), output inductor (L1), output capacitor (C4, C7), sense resistor (R17), and ORFET (Q1). Diode (D2) and capacitor (C6)
form a peak detector that drives the ORFET. Capacitors (C23, C64, C67) provide high frequency decoupling to lower EMI.
Diodes (D15-D18) rectify the input current signal to sense the primary current and resistor (R10) converts the current into a
voltage. The over current flag trips at 1.2V. Thermistor (RT1) is placed close to the ORFET on the board allowing over
temperature protection functionality to be implemented.
Also present on the secondary is the current sharing circuitry, flag LEDs (D11-D12), communications port to the software
through the I2C bus.

Daughter card
There is a 4 pin connector for I2C communication. This allows the software to communicate with the evaluation board through
the USB port of the PC. Instead of using an auxiliary supply, the board uses the 5V input from the USB port, and generates
3.3V using an LDO for the ADP1043A. The synchronous rectifier drivers (ADP3624) are also powered by the 5V USB, but are
powered from the main 12V output after the output is in regulation.
Connectors (J8 and J9) are identical and are connected in parallel to each other to allow multiple boards to be connected to
the same I2C bus in a daisy chain configuration. Each board consumes between 150mA and 250mA depending on the
conditions. Particular care must be taken not to overload the USB 5V rail. Some USB ports are especially those connected at
a hub may shut down if overloaded, causing communication problems. In such cases an external 5V power supply is
recommended to power the board between test point TP44(+) and TP21(-).

SETTING FILES AND EEPROM
The ADP1043A communicates with the GUI software using the I2C bus.
The register settings (having extension .43r) and the board settings (having extension .43b) are two files that are associated
with the ADP1043A software. The register settings file contains information that govern the functionality of the part such as the
over voltage and over current limits, softstart timing, PWM settings etc. The ADP1043A stores all its settings in the EEPROM.
When the ADP1043A is connected to the USB dongle the LDO powers the I.C. and the GUI downloads the settings from the
registers of the ADP1043A so that the state of the part is known. It is possible to save these settings in a file for later use.
Older register settings are overwritten when new files are loaded.
The EEPROM on the ADP1043A does not contain any information about the board, such as current sense resistor, output
inductor and capacitor values. This information is stored in board setup file (extension .43b) and is necessary for the GUI to
display the correct information in the „Monitor‟ tab as well as „Filter Settings‟ window. The ADP1043A does not need this
information in order to operate, but the GUI will need it in order to show the values correctly in the „Flags and Settings‟ window.
The entire status of the power supply such as the ORFET and synchronous rectifiers enable/disable, primary current, output
voltage and current can be thus digitally monitored and controlled using software only. Always make sure that the correct
board file has been loaded for the board currently in use.
Each ADP1043A chip has trim registers for the temperature, input current and the output voltage and current. These can be
configured during production and are not overwritten whenever a new register settings file is loaded. This is done in order to
retain the trimming of all the ADCs for that corresponding environmental and circuit condition (component tolerances, thermal
drift, etc.). A guided wizard called the „Auto Trim‟ is started which trims the above mentioned quantities so that the
measurement value matches the valued displayed in the GUI to allow ease of control through software.
In the following pages it will be shown that the ADP1043A can be easily programmed to modify the behavior of the PSU under
different fault and load conditions without any hardware changes. All the changes are purely through software and do not
require desoldering components and replacing them with new values to specify a different operating condition

SETUP
NOTE: DO NOT CONNECT THE USB CABLE TO THE EVALUATION BOARD UNTIL THE SOFTWARE HAS
FINISHED INSTALLING
1)
Install the ADP1043A software by inserting the installation CD. The software setup will start automatically and a guided
process will install the software as well as the USB drivers for communication of the GUI with the IC using the USB
dongle.
2)
Insert the daughter card in connector J1 as shown in Figure 5.
3)
Ensure that the PS_ON switch (SW1 on schematic) is turned to the OFF position. It is located on the bottom left half of the
board (Figure 5).
4)
Connect the evaluation board to the USB port on the PC using the “USB to I2C interface” dongle as shown in Figure 2.
5)
The software should report that the ADP1043A has been located on the board. Click “Finish” to proceed to the Main
Software Interface Window. The serial number reported on the side of the checkbox indicates the USB dongle serial
number. The windows also displays the device I2C address.
5. If the software does not detect the part it enters into simulation mode. Ensure that the connecter is connected to J8/J9 (on
main board) or J7 (on daughter card). Click on „Scan for ADP1043A now‟ icon (magnifying glass) located on the top right hand
corner of the screen.
5. Click on the “Load Board Settings” icon (fourth button from the left) and select the ADP1043AFB100_I_0710.43b file. This
file contains all the board information including values of shunt and voltage dividers. Note: All board setting files have an
extension of .43b
ADP1043A 100Watt
PRD1266
6. The IC on the evaluation board comes preprogrammed and this step is optional. The original register configuration is
stored in the ADP1043AFB100_I_0710.43r register file. (I and 0710 stand for the hardware revision number and the
month/year date code respectively). Note: All register files have an extension of .43r. The file can be loaded using the second
icon from the left in Figure 10.
7. Connect a DC power source (48VDC nominal, current limit to 5A) and an electronic load at the output set to 8 Amperes.
8. Connect a voltmeter on the output (connectors J4 and J5) and a differential scope probes (optional) between test points
TP16 and TP17. Ensure that the differential probes are used and the ground of the probes are isolated if measurements are
made on the primary and secondary side of the transformer simultaneously).
9. Turn the PS_ON switch (SW1 on schematic) to the ON position.
10. The evaluation board should now up and running, and ready for evaluation. The output should now read 12 VDC.
11. Click on the „MONITOR‟ tab and then on the Flags and readings icon. This windows provides a snapshot of the entire state
of the PSU in a single user friendly window.
During power up, the ADP1043A is connected to the USB port (5V) and the LDO powers the IC. It takes 20µsec for VCORE
(pin 26) to reach an internal voltage of 2.5V. After this, the I.C. downloads the contents of the registers into the EEPROM. After
this the softstart ramp begins.
After successful startup and in steady state condition, 5 LEDs on the board to provide to the user the status of the board. All
except the D12 (or FLAGIN) LED will be turned ON indicating that there are no faults detected such as over voltage or over
current. In case of a fault the POOD1 or PGOOD2 LEDs will be turned OFF indicating that some flag has tripped due to an out
of bounds condition. The monitor window will display the appropriate state of the PSU.

ADP1043A PROGRAMMING SOFTWARE
The goal of this evaluation kit is to allow the user to get an insight into the flexibility offered by the extensive programming
options offered by the ADP1043A. Several test points on the board allow easy monitoring of the various signals. The user can
also use the software to program multiple responses (such as disable power supply or turn off ORFET) for various fault
conditions.
The following sections give provide a good overview of the software as well as the test data experiments that the user might
typically evaluate. There are 9 main windows (blue icons in figure below) where the user can use to program and evaluate the
PSU. They can be accessed from the Setup window in the GUI.

PRD1266
FLAGS SETTINGS CONFIGURATIONS
The following state machine diagram provides a graphical idea as to how the flags in the ADP1043A operate and hence gain
insight into the working of the IC.
Basically when a flag is triggered, the controller waits for a programmable debounce time before taking any action. The
response to each flag can be programmed individually. The flags can be programmed in a single window by hitting the FLAG
SETTINGS icon in the MONITOR tab in the GUI and the state of the power supply can be monitored by clicking on the FLAGS
AND READINGS icon in the MONITOR tab.
ADP1043A 100Watt
PRD1266
This monitor window shows all the fault flags (if any) and the readings in one page. The „Get First Flag‟ button determines the
first flag that was set in case of a fault event.
The ADP1043A is programmed to respond to the various fault conditions in the Flag Settings Window.
ACTION: Ignore Flag Completely, Disable Synchronous Rectifiers, Disable ORFET, and Disable power Supply are the
operations available in this column.
TIMING: This defines if an ACTION is taken immediately or after a debounce. Debounce is a term used for a wait period in
digital circuitry. After a flag signal is detected, the debounce routine checks if the flag signal remains in its changed state for the
entire programmed debounce period before taking any action. This prevents the ADP1043A from reacting to false positives.
RESOLVE ISSUE: This determines the operation of the PSU after the fault is cleared. Hysteretic or latching options are
available.

GENERAL SETTINGS AND SOFTSTART
This section programs the PS_ON turn on and softstart timing. The power supply (PSU) can be turned on with a manual switch
(hardware PS_ON), a software enabled switch (SW PS_ON), or both with a programmable delay. It contains the capability of
adding a soft start to the primary and secondary switches (synchronous rectifiers) and also displays the temperature of the
thermistor for the over temperature protection. It is not recommended to use the soft stop ramp as it overrides any protection
features such as overcurrent protection.
Some test results are provided to better appreciate the flexibility of part. In addition to these some suggestions for further
exploration are also provided.
A.
PS_ON Turn on Delay: Figure 16 and Figure 17 show the startup sequence with a 0.5 second and 2 second delay
respectively. This test was conducted by monitoring the PSON signal (TP29), the output voltage (J4 and J5) and
setting a programmable delay using the drop down menu. Monitoring the synchronous rectifier (test point SR1 and
SR2) is optional.
ADP1043A 100Watt
B.
PRD1266
Softstart ramp and SR blanking: Figure 18 and Figure 19 show the startup sequence with the synchronous
rectifiers enabled/disabled with a 20ms and 40ms softstart ramp respectively.
This test was conducted by monitoring the output voltage (J4 and J5) and the test points SR1/SR2 during a startup
condition. The „Blank SR during softstart check box and the „Softstart ramp rate‟ dropdown menu were appropriately
selected.
C.
SR enable during softstart: Figure 20 shows the startup sequence with the synchronous rectifiers enabled during
softstart. This test was conducted by monitoring the output voltage (J4 and J5) and the synchronous rectifier test
points test points (SR1, SR2) during a startup condition. The „Blank SR during softstart check box was left unchecked.
ADP1043A 100Watt
D.
PRD1266
SR softstart: This test shows the capability of the softstart ramp or fade in sequence applied to the synchronous
rectifiers. The „Enable SR softstart‟ button was checked. Figure 21 and Figure 22 show a zoomed in snapshot of the
duty cycle at the beginning and end of the softstart ramp
Additional things to try:
a)
Implementation of different softstart timings in combination with different PS_ON delays.
b)
Disabling „Soft Start Always‟ and evaluating the performance after a fault like UVP/OVP disables the PSU.
c)
Trimming the RTD register by measuring the temperature at the OrFET and changing the trim setting.
d)
Disable the OrFET allowing its body diode to conduct the output current. Then set different OTP thresholds.
e)
Enable Softstart always and see the PSU start a softstart ramp everytime a fault such as a temporary short circuit.
ADP1043A 100Watt
PRD1266
PWM AND SR SETTINGS
The switches on the primary and the synchronous rectifier timings are controlled in this window. This window programs the
switching frequency, timings of the synchronous rectifier, the type of modulating edge (rising or falling), modulation type
(positive or negative). The IC can be programmed to run at a fixed duty cycle.
The Pulse Skipping mode is activated when the controller requires a duty cycle less than the „modulation low limit‟ to maintain
output regulation.
Note 1: All the signals shown below represent the gate drive signals at the output pins of the IC.
Note 2: Although the switching frequency can be increased, the software does not account for the dead times and these have
to be programmed manually by measuring the propagation delays between the output of the ADP1043A and the gate of the
MOSFET. A 200nsec delay is conservative for the evaluation board.
Things to try:
a)
Referring to the schematic, turning on QA and QB for the entire period of Ts/2 (with appropriate deadtimes) and
modulating only the bottom MOSFETs.
b)
Enabling/Disabling Pulse skipping mode and measuring standby power (by disabling the LEDs on the board
additional power can be saved).
c)
Doubling the switching frequency (see accompanying file 200KHz with VS balance.43r) Note: The board is designed
to operate at switching frequencies of up to 200kHz with air flow cooling (i.e. a fan). Beyond that, frequency damage
to the FETs may occur.
d)
Programming an imbalance in the ON times of the MOSFETs of each branch and evaluating Volt-Second balance.
e)
Measuring the effect on standby power by reducing the „Modulation Low Limit‟ with/without pulse skipping.
f)
Run the software in simulation mode and program the PWM settings for a different topology.

PRD1266
CS1 OR INPUT CURRENT SETTING
The input current settings are accessed using the CS1 Settings block. It is used to program the fast and accurate ADCs for
pulse by pulse current limiting, leading edge blanking, and enable the volt-sec balance correction to the bottom MOSFETs of
the full bridge converter and/or the synchronous rectifiers.
Some tests are provided to better appreciate the flexibility of part. In addition to these, some suggestions for further evaluation
are also provided.
A.
CS1 Accurate OCP: Figure 25 shows the CS1 accurate OCP flag and a reenable after 1 second
This test was conducted by setting the CS1 accurate OCP limit of 2.76A (drop down menu in the GUI) which is lower
than the current at minimum voltage. Then the input voltage was ramped down from 60V until the OCP limit was
triggered. . Monitoring the PWM signal at test point OUTA clearly shows the shutdown of the PWM.
ADP1043A 100Watt
B.
PRD1266
Volt Second Balance feature: The CS1 settings window has the volt second feature that measures the average
current in each leg of the full bridge topology. The algorithm reduces (or increases) the conduction time of each
branch by varying the pulse width of the MOSFET gate signals applied to OUTB and OUTD depending if there was
an increase (or decrease) of current in the corresponding branch. A maximum of 80nsec can be accounted for by this
algorithm.
This test was conducted by purposely introducing a mismatch of 75nsec in the PWM settings window. This mismatch
clearly shows that the transformer is close to saturation on one end. Figure 27 shows the imbalance and Figure 28
shows the corrected imbalance after the feature was turned on in the GUI by closing the switch. The primary current
can be measured using a current probe and by using a small loop of wire in place of jumper L3 or C10 on the board.
ADP1043A 100Watt

PRD1266
CS1 Fast OCP: Figure 29 and Figure 30 show the CS1 fast OCP tripping under a shorted output.
In this test the CS1 pulse by pulse current limit was tested during a shorted output. A shutdown was programmed
after 4 repetitive OCP limits were triggered.
Additional things to try:
a)
Programming an external FLAGIN to trip the CS1 fast OCP comparator.
b)
Enabling/Disabling Volt-Second balance and its associated gain.
c)
Measuring peak output power at maximum input voltage and by decreasing/increasing the debounce value.
d)
Use a blocking capacitor (0.47µF/100V, metal film) and check the effect of changing the gain in the Volt-second
balance on the current waveform.
e)
Choosing a different value of R10 (on schematic) to get a different range of protection.
ADP1043A 100Watt
PRD1266
CS2 OR OUTPUT CURRENT SETTING
The output current settings window is accessed using the CS2 Settings block. This window also features trimming registers ,
line impedance feature, threshold for over current protection (OCP), the light load threshold, and constant current mode.
The following waveforms display some of the features that can be programmed using this window.
A.
Over Current Protection (OCP): Figure 32 and Figure 33 show hysteretic and latching OCP respectively.
An over current condition can be easily created by shorting the load or increasing the output current beyond the OCP
limt. Different reactions to the fault can be programmed by either re-enabling the PSU after 1 second or a complete
shutdown through the drop down menus in the GUI.
ADP1043A 100Watt
B.
PRD1266
Constant Current Mode: Figure 34 shows the output voltage ramping down linearly by 60% during constant current
mode.
Closing the switch on the trace connected to the Constant Current Block enables CC mode. In this the output voltage
linearly drops by 60% of its nominal value when the load current reaches 90% of the OCP limit. In this example, the
IC enters CC mode when the load was set to 9.5A which is 94.7% of the OCP limit and output voltage drops to 7 Volts
in during CC.
Additional things to try:
a)
Setting a different light load thresholds and measuring its effect on efficiency
b)
Using the line impedance feature to simulate the voltage drop through a 2 foot output cable.
c)
Reducing the current sense resistor value (R17) and changing the range of the full scale voltage drop on CS2+ and
CS2-
d)
Increasing the debounce time on CS2 OCP limit and measuring the peak output power during a short circuit test.
e)
Setting different OCP limits and setting a different response such as disable SyncRec
ADP1043A 100Watt
PRD1266
LIGHT LOAD MODE
The ADP1043A can be programmed to optimize performance when the output current drops below a certain level. The light
load threshold is set in a manner to reduce the losses in the synchronous rectifiers to enter into DCM and reduce the power
loss in the SR drivers and increase efficiency. A hysteresis is provided on this threshold to avoid oscillations.
When operating in light load mode the corresponding flag will be set as well as the SR off flag as shown in the monitor window
(Synchronous rectifiers turned red in figure below), and the light load filter settings will be used. Using this in combination with
Pulse Skipping aids in reducing standby power consumption. The ACSNS flag is used to sense the voltage at the front side of
the inductor connected to the transformer (T2).

PRD1266
OUTPUT VOLTAGE SETTINGS
This window sets all the parameters related to the output voltage, including trimming, overvoltage protection (OVP) and
undervoltage protection (UVP) protection. There are three points where the output voltage is sensed using the ADP1043A
namely, before the ORFET (local OVP), after the ORFET (also local OVP), and at the load (remote OVP). An over voltage
condition at the load is termed as remote OVP whereas at the other two locations is termed as local OVP.
The following waveforms display some of the features that can be changed using this window.
A.
Under Voltage Protection (UVP): Figure 39 and Figure 40 show latching and hysteretic UVP respectively.
This test can be conducted in a number of ways, the simplest of which would be to set the „VS3 Output Voltage
Setting‟ under the programmed UVP threshold using the drop down menu in the GUI. Alternately, the duty cycle can
be clamped to a lower value than its required value. Under certain conditions even a shorted load or an internal short
(shorting the synchronous rectifiers) can cause a UVP condition. Hysteretic (enable after 1 sec) and latching (remain
disabled, only PS_ON can reenable) are the programmed choices for the faults.
ADP1043A 100Watt
B.
PRD1266
Over Voltage Protection (OVP): Figure 41 and Figure 42 show latching and hysteretic OVP respectively.
This test can be easily performed setting the VS3 regulation point beyond the OVP threshold. Another method how
an OVP flag can be tripped is by suddenly opening the control loop (open R10 or short R11 on the daughter card).
Hysteretic (enable after 1 sec) and latching (remain disabled, only PS_ON can reenable) are the programmed
choices for the faults in the drop down menu provided in the GUI.
Additional things to try:
1.
Using Auto trim to precisely set the voltage at the terminals of the board.
2.
Setting OVP and UVP limits to ±5% of nominal output voltage and measuring its effect on startup
3.
Regulating with VS3 at all times and evaluating the transient response.
4.
Use this voltage continuity feature to detect a voltage drop more than 100mV between VS1 and VS2 or VS2 and
VS3.

DIGITAL FILTER SETTINGS AND TRANSIENT ANALYSIS
The digital filter can be changed using the software by manipulating the position of the poles and zeros (red and green circles
in figure below) in the Laplace domain. The ADP1043A allows two different sets of compensation to be programmed, one at
light load and one at heavy load.
A type 3 compensation is implemented in the ADP1043A. The first pole (to eliminate steady state error) is indirectly accessed
through the placement of the first zero. The second pole can be freely placed, but the third pole (high frequency gain) is fixed
at half the switching frequency. There is an additional constraint in moving the poles and zeros and it is that the software
allows the poles and zeros to be moved only in a manner that keeps the slopes between them equal to ±20dB/dec.
WARNING: While varying the compensation parameters is possible while the part is running, the wrong combination
of parameters can cause the system to become unstable.
The following figures are provided to demonstrate the performance of the PSU as well as the ease with which the GUI can be
used to change the dynamic response of the system.
A.
Closed Loop System: Figure 43 and Figure 44 show the bode plot of the system.
The validity of this plot depends highly on the proper characterization of the output inductor and capacitor and their
respective parasitic components namely the DC resistance and ESR. The GUI displays the closed loop crossover
frequency, phase margin as well as individual gain and phase plots for the LC filter, digital filter and the closed loop
scenarios.

Transient Response for load step: Figure 45 and Figure 46 show the transient response at 36 and 60VDC
respectively.
A dynamic load from 1-8A (slew rate 1A/µs) at a frequency of 20-25Hz can be set up to conduct this test. The output
voltage must be measured at the connectors J4 and J5 with very small loop area between the positive and negative
of the probes to minimize noise.
C.
Transient Response under DCM/CCM transition: Figure 47 shows the dynamic response of the system under a
load step of 0.2-5A (slew rate1A/µs). A low starting current is chosen so that the converter is forced to disable the
synchronous rectifiers due to the light load threshold setting in the CS2 window. In contrast, Figure 48 shows the
response with the light load threshold set at 0A (SR always on). This forces the output inductor current to be
continuous and the converter remains in CCM despite the load condition drawing energy from the output capacitor to
charge the inductor.

PRD1266
Additional things to try:
a)
Tweaking the light load transient response (0-500mA step load).
b)
Increasing the crossover frequency and measure transient response
c)
Measuring transient response under different load steps
d)
Increasing the phase margin to 60 degrees by cancelling the double pole of the output LC filter by the two zeros of
the Type 3 compensation.
e)
Measuring the transient response (0.2A - 8A) by enabling the light load mode at 0.0A (SR always enabled) thus
keeping the output inductor in CCM regardless of the load.
f)
Measuring the dynamic response at 200KHz switching frequency.

ORFET SETTINGS
The ADP1043A includes features such as hot swapping as well as protection against a reverse current from other PSUs
connected on the same bus with the use of active ORing (ORFET). This window sets the turn on condition of the OrFET
depending upon the voltage threshold across it as well as its turn off depending upon the reverse current flowing in the current
+
sense resistor CS2 - CS2 . This enables hot swapping and allows additional PSUs to be connected to the same bus without
any interruption with sufficient protection.
The following waveforms display some of the features that can be changed using this window.
A.
Load OVP action on OrFET: Figure 50 shows the OrFET being disabled when a bus voltage is greater than the local
voltage. A DC power supply can be connected to the output terminals of the board (J4, J5). Care should be taken to
ensure that the output voltage is not beyond the voltage rating of the output capacitor (C7) and the absolute
maximum VCC rating of the SR driver (U1). Here the load OVP flag is used to protect the PSU by disabling the
OrFET. The body diode of the MOSFET (Q1) is reversed biased during this condition.

PRD1266
B.
Internal short circuit action on OrFET: Figure 51 and Figure 52 shows the OrFET disabled during an internal short
circuit and its corresponding flag. An internal short of the synchronous rectifiers can be can be simulated in the PWM
settings or by physically shorting the drain pin of Q2 and Q3. The CS1 fast OCP or the UVP flags can be set to
disable the OrFET.
C.
UVP action on OrFET: Figure 53 and Figure 54 show the disabled OrFET signal during a UVP fault and reenable
after the flag is cleared.
Additional things to try:
a)
Disable OrFET using CS1 OCP, Load UVP or fast OrFET when an internal short circuit occurs.
b)
Disable OrFET using VS3 when VOUT> OVP limit.
c)
Disable ORFET using ACSNS in light load mode to minimize light load standby consumption.
