DC-DC Converter
The BusQor^® SQ60120QPA28 bus converter is a
next-generation, board-mountable, isolated, fixed
switching frequency dc-dc converter that uses
synchronous rectification to achieve extremely
high conversion efficiency. The power dissipated
by the converter is so low that a heatsink is not
required, which saves cost, weight, height, and
application effort. The SQ BusQor series provides
an isolated step down voltage from 48V to a
semi-regulated 12V intermediate bus. BusQor
converters are ideal for customers who need
multiple outputs and wish to build or buy point of
load converters to work with a 12V rail. RoHS
Compliant (see last page).
