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).

Operational Features

• Ultra-high efficiency, 95% at full rated load current

• Delivers up to 28 A (336 W) of output current (power) with

minimal derating - no heatsink required

• Input voltage range: 36 – 75 V

• Fixed frequency switching provides predictable

EMI performance
