Technical
Specification
SQ60120QPB33
36-75 V
Input
100 V
Transient Input
12 V
Output
396 W 2250 V dc Quarter-brick
Max Power
Isolation
DC-DC Converter
The SQ60120QPB33 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 SQ BusQor series
provides an isolated step down voltage from 48 V to a semi-
regulated 12 V 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 12 V
rail. RoHS Compliant (see last page).
