Output Voltage Trim

Output Voltage Sequencing

The Formula for Output Voltage Trim

The SEQ pin can be used when master-slave power-supply tracking isrequired.
The voltage applied to the SEQ pin should be scaled down by the sameratio as used to scale the output voltage down to the reference voltage ofthe module. This is accomplished by an external resistive divider
connected across the sequencing voltage before it is fed to the SEQ pin.
The minimum recommended delay between the ON/OFF signal and thesequencing signal is 10ms to ensure that the module output is ramped up
according to the sequencing signal. This ensures that the module soft-startroutine is completed before the sequencing signal is allowed to ramp up.
When an analog voltage is applied to the SEQ pin, the output voltage tracks
this voltage until the output reaches the set-point voltage. The final valueof the SEQ voltage must be set higher than the set-point voltage of themodule. The output voltage follows the voltage on the SEQ pin on a oneto-one basis. By connecting multiple modules together, multiple modules
can track their output voltages to the voltage applied on the SEQ pin.
To initiate simultaneous shutdown of the modules, the SEQ pin voltage islowered 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.

overcurrent, short-circuit, UVLO, overvoltage and undervoltage,
overtemperature, or when the output is not regulated (such as an prebiasoutput). An external pullup resistor to VDD or to an external rail is required.
Included is a 20-μs deglitch filter. PGOOD pin can be connected through apullup resistor suggested value 100kΩ) to a source of 5VDC or lower.

The SEQ pin can be used when master-slave power-supply tracking isrequired.

Synchronization

Remote ON/OFFThe 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, with the converter being synchronized by the rising edgeof the external signal. The Electrical Specifications table specifies therequirements of the external SYNC signal. If the SYNC pin is not used, themodule should free run at the default switching frequency. If synchronization
is not being used, connect the SYNC pin to GND.

The circuit configuration for using the Remote On/Off pin is shown infigure.
And the logic type active mode as the description below.

Pick and PlaceNozzle

The 12A Open Frame modules use an open frame construction and aredesigned for a fully automated assembly process. We suggest the pick andplace operations is inductor.

The module weight has been kept to a minimum by using open frame
construction. Variables such as nozzle size, tip style, vacuum pressure andplacement speed should be considered to optimize this process.

MSL Rating

Lead-free Reflow Profile

The 12A Open Frame modules have a MSL rating of 3.

Storage and Handling

The recommended storage environment and handling procedures formoisture-sensitive surface mount packages is detailed in J-STD-033(Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface
Mount Devices).

Power Systems will comply with J-STD-020 (Moisture/Reflow Sensitivity
Classification for non-hermetic Solid State Surface Mount Devices) for bothPb-free solder profiles and MSL classification procedures. This standard
provides a recommended forced-air-convection reflow profile based on thevolume and thickness of the package. The suggested Pb-free solder paste isSn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu
solder is shown. Soldering outside of the recommended profile requires
testing to verify results and performance.

Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 3or 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 conditionsof ≦ 30°C and 60% relative humidity 168 hours varies according to the MSLrating (see J-STD-033). The shelf life for dry packed SMT packages will be amaximum of 12 months from the bag seal date, when stored at the following
conditions: < 40° C, < 90% relative humidity.
