Description
Demonstration circuit 2204A is a very compact demo
board that showcases five different Linear Technology
devices – LTM4675, LTM4676A, LTM4677, LTM4620A
and LTC2974. These devices cover various product
lines including DC/DC µModule® regulator with digital
power system management (LTM4675, LTM4676A and
LTM4677), high current analog DC/DC µModule regulator
(LTM4620A) and I2C/SMBus/PMBus power system managers with EEPROM (LTC2974). Please see data sheets
for more detailed information.
DC2204A contains seven different rails, including six
single-phase rails and one dual-phase single-output rail
from LTM4677. The µModule regulators used on this
board only require only a few external components and
therefore can greatly save the footprint, reduce the design
effort and improve the system reliability. The LTC2974
monitors LTM4620A’s output voltage, load current and
temperature through external diodes.
DC2204A powers up to default settings and produce power
based on configuration resistors without the need for any
serial bus communication. This allows easy evaluation of
the DC/DC µModule regulators. There is also a connector
to wall adapter which allows easy demonstration without
DC/DC power supply. Multiple DC2204A boards can be
cascaded together to form a high channel count power
supply.
To fully explore the extensive power system management features of the part, download the GUI software
LTpowerPlay™ onto your PC and use LTC’s I2C/SMBus/
PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on the fly
and store the configuration in EEPROM, view telemetry of
voltage, current, temperature and fault status.

*Note: The LTM4675, LTM4676A and LTM4620A can provide outputs up to 5.5V (5.3V for LTM4620A); however 4V-rated output ceramic capacitors are
used on board. When running at higher output voltage, 6.3V-rated output capacitors should be used.
**Note: When running at full load, forced air flow is needed.
Quick Start Procedure
Demonstration circuit 2204A is easy to set up to evaluate the performance of four µModules. The following procedure
describes how to set up a DC2204A demo system. Please refer to Figure 2 for the test setup and Figure 3 for the
DC2204A top side details.

DEMO MANUAL DC2204A
Quick Start Procedure
1. Download and install the LTpowerPlay GUI;
2. Connect the DC1613A dongle to the DC2204A using the 12-pin ribbon cable;
3. With power off, connect the input power supply (4.5V to 15V) to VIN and GND;
4. Launch the LTpowerPlay GUI (the LTpowerPlay Main Interface is shown in Figure 4):

DEMO MANUAL DC2204A
Quick Start Procedure
a. The GUI will automatically identify the DC2204A and build a system tree for each PSM µModules and manager.
The system tree on the left hand side will look as below:
b. A green message box will be displayed momentarily in the lower left hand corner confirming that the DC2204A is
communicating.
c. Save the demo board configuration to a (*.proj) file by clicking the Save icon. This creates a backup file.
5. The CONTROL switch is configured to control all seven rails. Slide the switch to ON to enable, OFF to disable all rails.

DEMO MANUAL DC2204A
Common Demo Board Operations
DC2204A On-Board LEDs
Each individual rail on DC2204A has its own green power-good LED indicator (D1 through D7). There is another green
LED (D12) which is on after VIN supply is applied. Two red LEDs (D12 and D13) will illuminate when an alert or a fault
has occurred.
Margin All Rails
The digital power products on the DC2204A not only monitor each of their respective outputs but can margin the
outputs either high or low. Margining is the operation that moves a rail either up or down for testing purposes. It allows a system to be fully characterized over supply limits without the use of external hardware or resources. The GUI
provides an easy way to margin all rails high or all low by clicking one of four buttons. To invoke the margining dialog,
click the GroupOp icon in the
toolbar.
Then the user can choose Margin High, Margin Low or some other operations to all the devices from the window in
below.

DEMO MANUAL DC2204A
Common Demo Board Operations
The telemetry window in the lower right hand corner shows the effect of the margin high or margin low operation. The
following screen shot shows all rails going from nominal set points to margin high, margin low and back to nominal
voltages.
Creating and Clearing a Fault
There is a pushbutton on the DC2204A board which is used to force a fault and demonstrate the demo board’s ability
to detect it and respond according to the configuration.
When pressing this button (SW3), it creates a VOUT_UV fault on Vo6, by pulling COMP pin low externally. The user
should see Vo6 output power off, the green LED (D6) off and the red LED (D12) on. After a retry period, the rail will
be back on.
To clear a fault, the user may click the CF icon in the GUI or simply push the RESET pushbutton on the demo board.
In both cases, the red (+) on the CF icon and alert LED on the board will be cleared. The user will notice that all rails
are automatically re-enabled after a programmable retry period.
Reset the DC2204A
A reset pushbutton is provided on the board. To reset all devices on the DC2204A board and reload the EEPROM
contents into operating memory (RAM), press RESETB (SW2) on the DC2204A.
