• The +Out and –Out

power buses should be

designed to minimize

and balance parasitic

impedance from each

module output to the

load.

• At the discretion of the

power system designer,

a subset of all modules

within an array may be

configured as slaves by

shorting SC to –Out.

• Do not use output

ORʼing diodes with

MicroMods.

• This module is designed for point of load regulation, where remote sensing

is not required. Active voltage drop compensator, as shown here, may be

used in applications with significant distribution losses. Contact applications

engineering for specific values.

Please consult with the Micro Family Isolated Remote Sense Application Note

for additional information.

* Pin style designator follows the “B” after the output power and precedes the baseplate designator.
