Description
The FC050A, FC100A, and FC150A Power Modules are dc-dc converters that operate over an input voltage
range of 18 Vdc to 36 Vdc and provide a precisely regulated dc output. The outputs are fully isolated from the
inputs, allowing versatile polarity congurations and grounding connections. The modules have maximum power
ratings from 50 W to 150 W at a typical full-load efciency of 81%.
Built-in ltering, for both the input and output of each device, eliminates the need for external lters. Two or more
modules may be paralleled with forced load sharing for redundant or enhanced power applications. The package,
which mounts on a printed-circuit board, accommodates a heat sink for high-temperature applications.
