Trim
Without an external resistor between Trim and GND pins, the output of the module will be 0.6Vdc.
Rtrim
for a desired output

Safety Considerations
For safety agency approval the power module must be installed in compliance with the spacing and separation requirements
of the end-use safety agency standards listed on the first page of this document. 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 units were tested using an external Littelfuse 456 series fast-
acting fuse rated at 30A in the ungrounded input.
Tunable Loop
The module is designed for 200uF capacitor on its output. For applications where more than 200uF capacitors would be used
on the output, an additional Resistor (Rtune) and Capacitor (Ctune) would be required in the circuit schematic to compensate
for the additional capacitance. The placement is between the Sense+ pin and Trim pin as per figure below:

RTune
The recommended values for Rtune and Ctune for
different amounts of external capacitance are as per
the table below:

PowerGood (PGOOD)
This is an open-drain output to indicate that the output voltage is within the regulation limits of the module. The PGOOD signal
will be de-asserted to a low state if any condition such as overtemperature, overcurrent or loss of regulation occurs that would
result in the output voltage going ±10% outside the setpoint value. If not used, leave unconnected.
Synchronization (SYNC)

SYNC

SIG_GND
Figure 4. External source connections to synchronize
switching frequency of the module
The module switching frequency can be synchronized to
a signal with an external frequency within a specified
range. Synchronization can be done by using the external
signal applied to the SYNC pin of the module as shown in
Fig. 39, with the converter being synchronized by the
rising edge of the external signal. The Module switches at
half the SYNC frequency. 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.
If
synchronization is not being used, connect the SYNC
pin to Sig_GND.

Bottom Side / First Side Assembly
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

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

Reflow Time (Seconds)
Storage and Handling
J-STD-033 Rev. A (Handling, Packing, Shipping and Use of
Moisture/Reflow Sensitive Surface Mount Devices) is
recommended. 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 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.
MSL Rating
The modules have a MSL rating of 2a.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. D
(Moisture/Reflow Sensitivity Classification for Nonhermetic Solid
State Surface Mount Devices) for both Pb-free solder profiles and
MSL classification procedures. The suggested Pb-free solder paste
is Sn/Ag/Cu (SAC).
The following profile is the recommended linear reflow profile
using Sn/Ag/Cu solder . Soldering outside of the recommended
profile requires testing to verify results and performance.
Post Solder Cleaning and Drying Considerations
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
