The BusQor® BQ60120HEx30 Exa series converter is a
next-generation, board-mountable, isolated, wide input,
regulated, fixed switching frequency DC-DC converter that
uses synchronous rectification to achieve extremely high
conversion efficiency. The BusQor Exa series provides an
isolated step down voltage from 35-75V to 12V with tight
output voltage regulation in a standard “half-brick” module
and is available in open-frame and baseplated version.
BusQor converters are ideal for customers who need
multiple outputs and wish to use point of load converters
to work with a 12V rail. The BusQor Exa series converters
offer industry-leading useable output current for powering
intermediate bus architechture systems. RoHS 6/6 compliant
(see page last page).
