• 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
connecting SC to –Out.
• Do not use output
OR’ing 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.
