• 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.

Please consult with the Micro Family Isolated Remote Sense Application Note

for additional information.
