12Vout 300W 2250V dc Quarter-brick
Continuous Input Transient Input Semi-Regulated Max Power
Isolation
DC-DC Converter
The SQ60120QEx25 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).
Operational Features
