Description
The 170A Digital TeraDLynxTM power modules are non-isolated dc-dc converters that can deliver up to 170A of output current.
These modules operate over a 7 to 14Vdc input range and provide a precisely regulated output voltage from 0.1 to 1.5Vdc. The
output voltage is programmable via an external resistor and/or PMBus control. Features include a digital interface using the
PMBus protocol, remote On/Off, adjustable output voltage, Power Good signal and overcurrent, overvoltage and overtemperature
protection. The PMBus interface supports a range of commands to both control and monitor the module. The module also
includes a real time compensation loop that allows optimizing the dynamic response of the converter to match the load with
reduced amount of output capacitance leading to savings on cost and PWB area.

To minimize input voltage ripple, ceramic capacitors are
recommended at the input of the module. Figure 31
shows the input ripple voltage for various output voltages
at 170A of load current with 4x470 + 12x22 + 12x4.7 µF

The 170A TeraDLynxTM module should be connected to a
low ac-impedance source. A highly inductive source can
affect the stability of the module. An input capacitance
must be placed directly adjacent to the input pins of the
module, to minimize input ripple voltage and ensure
module stability.

voltages with two input capacitor combinations at
170A load. Input voltage is 12V.
Output Filtering
These modules are designed for low output ripple voltage
and will meet the maximum output ripple specification with
minimum of 12 x 22 µF ceramic capacitors at the output of
the module. However, additional output filtering may be
required by the system designer for a number of reasons.
First, there may be a need to further reduce the output
ripple and noise of the module. Second, the dynamic
response characteristics may need to be customized to a
particular load step change.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the input
must meet SELV requirements. The power module has
extra-low voltage (ELV) outputs when all inputs are ELV.
The input to these units is to be provided with a slow-blow
fuse. When the input voltage is ≤ 8V, the recommendation is
to use two 25A Littelfuse 456 series or equivalent fuses in
parallel. For input voltages > 8V, a single 40A Littelfuse series
456 or equivalent fuse is recommended.
To reduce the output ripple and improve the dynamic
response to a step load change, additional capacitance at
the output can be used. Low ESR polymer and ceramic
capacitors are recommended to improve the dynamic
response of the module. Figure 32 provides output ripple
information for capacitance of ~3574µF (47µF (1210
ceramic) x 12 + 10µF (0805 ceramic) + 0.1uF (0402) x4 +
1000µF (polymer) x 3) at various Vo and a full load current of
170A. For stable operation of the module, limit the
capacitance to less than the maximum output capacitance
as specified in the electrical specification table. Optimal

7Vdc –14Vdc input; 0.1Vdc to 1.5Vdc output; 170A Output Current
Analog Feature Descriptions
The trim resistor is only determined during module
initialization and hence cannot be used for dynamic output
voltage adjustment
Remote On/Off
The TeraDLynx 170A module can be turned ON and OFF
either by using the ON/OFF pin (Analog interface) or through
the PMBus interface (Digital). The module can be configured
in a number of ways through the PMBus interface to react to
the ON/OFF input:
Module ON/OFF can controlled only through the
analog interface (digital interface ON/OFF
commands are ignored)
Module ON/OFF can controlled only through the
PMBus interface (analog interface is ignored)
Module ON/OFF can be controlled by either the
analog or digital interface
The default state of the module (as shipped from the factory)
is to be controlled by the analog interface only. If the digital
interface is to be enabled, or the module is to be controlled
only through the digital interface, this change must be made
through the PMBus. These changes can be made and
written to non-volatile memory on the module so that it is
remembered for subsequent use.
Analog On/Off
The 170A Digital TeraDLynxTM power modules feature an
On/Off pin for remote On/Off operation. With the Negative
Logic On/Off option, (see Ordering Information), the module
turns OFF during logic High and ON during logic Low. The
On/Off signal should be always referenced to ground.
Leaving the On/Off pin disconnected will turn the module
ON when input voltage is present. With the positive logic
on/off option, the module turns ON during logic high and
OFF during logic low.
Digital On/Off
Please see the Digital Feature Descriptions section.
Monotonic Start-up and Shutdown
The module has monotonic start-up and shutdown behavior
on the output for any combination of rated input voltage,
output current and operating temperature range.
Startup into Pre-biased Output
The module will start into a pre biased output on output as
long as the pre bias voltage is 0.5V less than the set output
voltage.
Analog Output Voltage Programming
The output voltage of the module is programmable to any
voltage from 0.1 to 1.5Vdc, as shown in Table 1, by
connecting a resistor between the Trim and SIG_GND pins of
the module as shown in Fig 33.
Without an external resistor between the Trim pin and
SIG_GND pins, the output of the module will be 0.1 Vdc. The
value of the trim resistor, RTrim for a desired output voltage,
should be selected as shown in Table 1.

The power module includes a sequencing feature, EZSEQUENCE that enables users to implement various types of
output voltage sequencing in their applications. This is
accomplished via an additional sequencing pin. When not
using the sequencing feature, leave it unconnected.
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will shut
down if the overtemperature threshold of 135 °C (typ) is
exceeded at the thermal reference point Tref. Once the unit
goes into thermal shutdown it will then wait to cool before
attempting to restart.

Figure 34. Circuit showing connection of the sequencing

When the sequencing voltage is applied to the SEQ pin, the
output voltage tracks this voltage until the output reaches
the set-point voltage. The final value of the sequencing
voltage must be set higher than the set-point voltage of the
module. The output voltage follows the sequencing voltage
on a one-to-one basis. By connecting multiple modules
together, multiple modules can track their output voltages
to the voltage applied on the SEQ pin.
The module’s output can track the SEQ pin signal with
slopes of up to 0.5V/msec during power-up or power-down.
To initiate simultaneous shutdown of the modules, the SEQ
pin voltage is lowered in a controlled manner. The output
voltage of the modules tracks the voltages below their setpoint voltages on a one-to-one basis. A valid input voltage
must be maintained until the tracking and output voltages
reach ground potential.

The module can support digital sequencing by allowing
control of the turn-on delay and rise times as well as turnoff and fall times,

The module switching frequency is capable of being

external signal applied to the SYNC pin of the module as
shown in Fig. 35, with the converter being synchronized by
the rising edge of the external signal. The Electrical
Specifications table specifies the requirements of the
external SYNC signal. If the SYNC pin is not used, the module
should free run at the default switching frequency.

Digital Compensator
The TJT170 module uses digital control to regulate the
output voltage. As with all POL modules, external capacitors
are usually added to the output of the module for two
reasons: to reduce output ripple and noise and to reduce
output voltage deviations from the steady-state value in the
presence of dynamic load current changes. Adding external
capacitance however affects the voltage control loop of the
module, typically causing the loop to slow down with
sluggish response. Larger values of external capacitance
could also cause the module to become unstable.
The TJT170 comes with default compensation values
programmed into the non-volatile memory of the module.
These digital compensation values can be adjusted
externally to optimize transient response and also ensure
stability for a wide range of external capacitance, as well as
with different types of output capacitance. This can be done
by two different methods.
1. By allowing the user to select among several pre-tuned
compensation choices to select the one most suited to
the transient response needs of the load. This selection is
made via a resistor RTune connected between the
RTUNE and SIG_GND pins as shown in Fig. 35. Table 2
shows various pre-tuned compensation combinations
recommended for various external capacitor
combinations.
2. Using PMBus to change compensation parameters in the
module.
Note that during initial startup of the module, compensation
values that are stored in non-volatile memory are used. If a
resistor RTune is connected to the module, then the
compensation values are changed to ones that correspond
to the value of RTUNE. If RTUNE is open however, no change
in compensation values is made. Finally, if the user chooses
to do so, they can overwrite the compensation values via
PMBus commands.
COMP1: Recommended for the case where all of the
output capacitance is composed of only ceramic
capacitors. The range of external output capacitance is
from 1470 µF to a maximum value of 17640 µF)
COMP2: For the most commonly used mix of ceramic
and polymer type capacitors that have higher output
capacitance in a smaller size. The range of output
capacitance is from 2564 µF to a maximum of 30564 uF.
This is the combination of output capacitance and
compensation that can achieve the best transient
response at lowest cost and smallest size. For example,
with the maximum output capacitance of 12 x 47µF
ceramics + 25 x 1000 µF polymer capacitors, and
selecting RTUNE = 5.36kΩ, transient deviation can be as
low as 25 mV, for a 50% load step (0 to 85A).
COMP3: Suitable for a mix of ceramic and higher ESR
polymers or electrolytic capacitors, with output
capacitance ranging from a minimum of 2204 µF to a
maximum of 30084 µF.
Selecting RTUNE according to Table 2 will ensure stable
operation of the module with sufficient stability margin as
well as yield optimal transient response.
In applications with tight output voltage limits in the presence
of dynamic current loading, additional output capacitance
will be required. Table 3 lists recommended values of RTUNE in
order to meet 2% output voltage deviation limits for some
common output voltages in the presence of an 85A to 170A
step change (50% of full load), with an input voltage of 12V.
Please contact your GE technical representative to obtain
more details of this feature as well as for guidelines on how
to select the right value of external RTUNE to tune the module
for best transient performance and stable operation for other
output capacitance values. Simulation models are also
available via the GE Power Module Wizard to predict stability
characteristics and transient response.
RTUNE
Recommended values of RTUNE for different output capacitor
combinations are given in Table 2. If no RTUNE is used, the
default compensation values are used.
The TJT170 pre-tuned compensation can be divided into
three different banks (COMP1, COMP2, COMP3) that are
available to the user to compensate the control loop for
various values and combinations of output capacitance and
to obtain reliable and stable performance under different
conditions. Each bank consists of 20 different sets of
compensation coefficients pre-calculated for different
values of output capacitance. The three banks are set up as
follows:

Value = Mantissa x 2 Exponent
PMBus Interface Capability
PMBus Addressing
The 170A TeraDLynx power modules have a PMBus
interface that supports both communication and control.
The PMBus Power Management Protocol Specification can
be obtained from www.pmbus.org. The modules support a
subset of version 1.1 of the specification (see Table 4 for a
list of the specific commands supported). Most module
parameters can be programmed using PMBus and stored as
defaults for later use.
Communication over the module PMBus interface supports
the Packet Error Checking (PEC) scheme. The PMBus master
must generate the correct PEC byte for all transactions, and
check the PEC byte returned by the module.
The power module is addressed through the PMBus using a
device address. The module supports 128 possible
addresses (0 to 127 in decimal) which can be set using
resistors connected from the ADDR0 and ADDR1 pins to
SIG_GND. Note that some of these addresses (0, 1, 2, 3, 4, 5,
6, 7, 8, 9, 10, 11 12, 40, 44, 45, 55 in decimal) are reserved
according to the SMBus specification and may not be
useable. The address is set in the form of two octal (0 to 7)
digits, with each pin setting one digit. The ADDR1 pin sets
the high order digit and ADDR0 sets the low order digit. The
resistor values suggested for each digit are shown in Table 3
(E96 series resistors are recommended). Note that if either
address resistor value is outside the range specified in Table
4, the module will respond to address 127.
The user must know which I2C addresses are reserved in a
system for special functions and set the address of the
module to avoid interfering with other system operations.
Both 100kHz and 400kHz bus speeds are supported by the
module. Connection for the PMBus interface should follow
the High Power DC specifications given in section 3.1.3 in the
SMBus specification V2.0 for the 400kHz bus speed or the
The module also supports the SMBALERT# response
protocol whereby the module can alert the bus master if it
wants to talk. For more information on the SMBus alert
response protocol, see the System Management Bus
(SMBus) specification.
The module has non-volatile memory that is used to store
configuration settings. Not all settings programmed into the
device are automatically saved into this non-volatile
memory, only those specifically identified as capable of
being stored can be saved (see Table 4 for which command
parameters can be saved to non-volatile storage).
Low Power DC specifications in section 3.1.2. The complete
SMBus specification is available from the SMBus web site,
smbus.org.
PMBus Data Format
For commands that set thresholds, voltages or report such
quantities, the module supports the “Linear” data format
among the three data formats supported by PMBus. The
Linear Data Format is a two-byte value with an 11-bit, two’s
complement mantissa and a 5-bit, two’s complement
exponent. The format of the two data bytes is shown below:

Operation (01h)
This is a paged register. The OPERATION command can be
used to turn the module on or off in conjunction with the
ON/OFF pin input. It is also used to margin up or margin
down the output voltage
PMBus Enabled On/Off
The module can also be turned on and off via the PMBus
interface. The OPERATION command is used to actually turn
the module on and off via the PMBus, while the
ON_OFF_CONFIG command configures the combination of
analog ON/OFF pin input and PMBus commands needed to
turn the module on and off. Bit [7] in the OPERATION
command data byte enables the module, with the following

January 3, 2017
CPA: Sets the action of the analog ON/OFF pin when turning
the controller OFF. This bit is internally read and cannot be
modified by the user
PMBus Adjustable Soft Start Rise Time
The soft start rise time of module output is adjustable in the
module via PMBus. The TON_RISE command can set the rise
time in ms, and allows choosing soft start times between 0
and 1000ms.
Output Voltage Adjustment Using the PMBus
Two PMBus commands are available to change the output
voltage setting. The first, VOUT_COMMAND can set the
output voltage directly. The second, VOUT_TRIM is used to
apply an offset to the commanded output voltage.
Since the output voltage can be set using an external RTrim
resistor as well, an additional PMBus command
MFR_VOUT_SET_MODE is used to tell the module whether
the VOUT_COMMAND is used to directly set output voltage
or whether RTrim is to be used. If MFR_VOUT_SET_MODE is
set to where bit position 7 is set at 1, then VOUT_COMMAND
is ignored and output voltage is set solely by RTrim. If bit 7 of
MFR_VOUT_SET_MODE is set to 0, then output voltage is set
using VOUT_COMMAND, and the value of RTrim is only used
at startup to set the output voltage.
The second output voltage adjustment command
VOUT_TRIM works in either case to provide a fixed offset to
the output voltage. This allows PMBus adjustment of the
output voltage irrespective of how MFR_VOUT_SET_MODE is
set and allows digital adjustment of the output voltage
setting even when RTrim is used.
For all digital commands used to set or adjust the output
voltage via PMBus, the resolution is 98µV.
Output Voltage Margining Using the PMBus
The output voltage of the module can be margined via
PMBus between 0 and 1.5V. The margining voltage can be
adjusted in 98µV steps.
PMBus Adjustable Overcurrent Warning
The module can provide an overcurrent warning via the
PMBus. The threshold for the overcurrent warning can be
set using the parameter IOUT_OC_WARN_LIMIT. This
command uses the “Linear” data format with a two byte
data word where the upper five bits [7:3] of the high byte
represent the exponent and the remaining three bits of the
high byte [2:0] and the eight bits in the low byte represent
the mantissa. The value of the IOUT_OC_WARN_LIMIT can
be stored to non-volatile memory using the
STORE_DEFAULT_ALL command.
Temperature Status via PMBus
The module provides information related to temperature of
the module through standardized PMBus commands.
Commands READ_TEMPERATURE1, READ_TEMPERATURE_2
are mapped to module temperature and internal
temperature of the PWM controller, respectively. The
temperature readings are returned in °C and in two bytes.

7Vdc –14Vdc input; 0.1Vdc to 1.5Vdc output; 170A Output Current
PMBus Adjustable Output Over, Under Voltage
Protection
The module has output over and under voltage protection
capability. The PMBus command VOUT_OV_FAULT_LIMIT is
used to set the output over voltage threshold. The default
value is configured to be 112.5% of the commanded output.
The command VOUT_UV_FAULT_LIMIT sets the threshold
that detects an output under voltage fault. The default
values are 87.5% of the commanded output voltage. Both
commands use two data bytes formatted in the Linear
format.
PMBus Adjustable Input Undervoltage Lockout
The module allows adjustment of the input under voltage
lockout and hysteresis. The command VIN_ON allows setting
the input voltage turn on threshold, while the VIN_OFF
command sets the input voltage turn off threshold. For the
VIN_ON command possible values are 7 to 14V and for the
VIN_OFF command, possible values are 6.75V to 14V . Both
VIN_ON and VIN_OFF commands use the “Linear” format
with two data bytes.
Measurement of Output Current, Output Voltage
and Input Voltage
The module can measure key module parameters such as
output current, output voltage and input voltage and
provide this information through the PMBus interface.
Measuring Output Current Using the PMBus
The module measures output current by using a signal
derived from the switching FET currents. The current gain
factor is accessed using the IOUT_CAL_GAIN command, and
consists of two bytes in the Linear data format. During
manufacture, each module is calibrated by measuring and
storing the current gain factor into non-volatile storage.
The current measurement accuracy is also improved by
each module being calibrated during manufacture with the
offset in the current reading. The IOUT_CAL_OFFSET
command is used to store and read the current offset. The
READ_IOUT command provides module average output
current information. This command only supports positive
output current, i.e. current sourced from the module. If the
converter is sinking current a reading of 0 is provided. The
READ_IOUT command returns two bytes of data in the
Linear data format.
Measuring Output Voltage Using the PMBus
The module provides output voltage information using the
READ_VOUT command. The command returns two bytes of
data in Linear format.
Measuring Input Voltage Using the PMBus
The module provides input voltage information using the
READ_VIN command. The command returns two bytes of
data in the Linear format.

User-Programmable Compensation Coefficients
The output voltage control compensation coefficients can
be changed by the user via PMBus commands. On startup,
the module uses stored values of the four compensation
parameters KD, KI, KP and ALPHA. If the module detects a
valid value of RTUNE connected to the module, the values of
KD, KI, KP and ALPHA are then changed to the appropriate
values. Beyond this, the user can use the PMBus commands
listed below to overwrite the values of KD, KP, KI and ALPHA.
MFR_SPECIFIC_KP: Allows the user to program the value of
the KP compensation coefficient. The allowed range is 32768 to 32767. The entire 16 bits are used to enter this
range of integer values in two’s complement binary format.
MFR_SPECIFIC_KI: Allows the user to program the value of
the KI compensation coefficient. The allowed range is 32768 to 32767. The entire 16 bits are used to enter this
range of integer values in two’s complement binary format.
MFR_SPECIFIC_KD: Allows the user to program the value of
the KD compensation coefficient. The allowed range is 32768 to 32767. The entire 16 bits are used to enter this
range of integer values in two’s complement binary format.
MFR_SPECIFIC_ALPHA: Allows the user to program the value
of the ALPHA compensation coefficient. The allowed range is
-256 to 256. The entire 16 bits are used to enter this range of
integer values in two’s complement binary format.
MFR_SPECIFIC_00: Returns information related to the type of
module and revision number. Bits [7:2] in the Low Byte
indicate the module type (001110 corresponds to the TJT170
series of module), while bits [7:3] in the high byte indicate
the revision number of the module.

Brief Description
MFR_VOUT_SET_MODE
Bit 7 used to determine whether output voltage is set using RTrim or the VOUT_COMMAND.
Bit 7: 1 – Output voltage is solely set by RTrim value and can be adjusted from set value
using the VOUT_TRIM command
Bit 7: 0 – Output voltage is solely set by VOUT_COMMAND and can be adjusted from set
value using the VOUT_TRIM command.
Bit 0: Used to indicate whether changes have been made to the Vout set point, PG On/Off
levels, margin levels or OV/UV fault/warning levels. A 1 in this position indicates that one or
more of the values have changed from the default. If this bit is 0, then the default values are
used.

Thermal Considerations
Power modules operate in a variety of thermal
environments; however, sufficient cooling should always be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of the
module will result in an increase in reliability. The thermal
data presented here is based on physical measurements
taken in a wind tunnel. The test set-up is shown in Figure
37. The preferred airflow direction for the module is in
Figure 38.

The thermal reference points, Tref used in the specifications
are also shown in Figure 38. For reliable operation the
temperatures at these points should not exceed 120°C. The
output power of the module should not exceed the rated
power of the module (Vo,set x Io,max).
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-Mounted
Power Modules” for a detailed discussion of thermal aspects
including maximum device temperatures.

Surface Mount Information
Pick and Place
The 170A TeraDLynxTM modules use an open frame
construction and are designed for a fully automated
assembly process. The modules are fitted with a label
designed to provide a large surface area for pick and place
operations. The label meets all the requirements for surface
mount processing, as well as safety standards, and is able
to withstand reflow temperatures of up to 300oC. The label
also carries product information such as product code,
serial number and the location of manufacture.
conditions of 30°C and 60% relative humidity varies
according to the MSL rating (see J-STD-033A). The shelf life
for dry packed SMT packages will be a minimum of 12
months from the bag seal date, when stored at the following
conditions: < 40° C, < 90% relative humidity.
Nozzle Recommendations
The module weight has been kept to a minimum by using
open frame construction. Variables such as nozzle size, tip
style, vacuum pressure and placement speed should be
considered to optimize this process. The minimum
recommended inside nozzle diameter for reliable operation
is 15mm. The maximum nozzle outer diameter, which will
safely fit within the allowable component spacing, is 22 mm.

Sn/Ag/Cu solder.
Bottom Side / First Side Assembly
Post Solder Cleaning and Drying Considerations
This module is not recommended for assembly on the
bottom side of a customer board. If such an assembly is
attempted, components may fall off the module during the
second reflow process.
Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The result
of inadequate cleaning and drying can affect both the
reliability of a power module and the testability of the
finished circuit-board assembly. For guidance on
appropriate soldering, cleaning and drying procedures, refer
to Board Mounted Power Modules: Soldering and Cleaning
Application Note (AN04-001).
Lead Free Soldering
The modules are lead-free (Pb-free) and RoHS compliant
and fully compatible in a Pb-free soldering process. Failure
to observe the instructions below may result in the failure of
or cause damage to the modules and can adversely affect
long-term reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for Nonhermetic
Solid State Surface Mount Devices) for both Pb-free solder
profiles and MSL classification procedures. This standard
provides a recommended forced-air-convection reflow
profile based on the volume and thickness of the package
(table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu
(SAC). The recommended linear reflow profile using
Sn/Ag/Cu solder is shown in Fig. 40. Soldering outside of the
recommended profile requires testing to verify results and
performance.
MSL Rating
The 170A TeraDLynxTM modules have a MSL rating of 3.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount packages
is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping
and Use of Moisture/Reflow Sensitive Surface Mount
Devices). Moisture barrier bags (MBB) with desiccant are
required for MSL ratings of 2 or greater. These sealed
packages should not be broken until time of use. Once the
original package is broken, the floor life of the product at
