Isolation

DC-DC Converter

converter is a next-generation, board-mountable, isolated,

fixed switching frequency DC/DC converter. The Exa series

offers industry leading power density for standard isolated

DC/DC converters with both a wide input range and a

tightly regulated output. Targeted for use in intermediate bus

architectures, this module supplies an isolated step down

voltage from 35-75V to 12V. This converter is available in

open-frame and base-plated versions. RoHS Compliant (see

page 14).
