DC-DC Converter

The BusQor^®BQ55090QTA27 bus converter is a next-

generation, board-mountable, isolated, fixed switching

frequencydc/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 BusQor series provides an isolated step down

voltage from 48V to 12 or 9.6V intermediate bus with no

regulation in a standard “quarter-brick” module. BusQor

converters are ideal for creating the mid-bus voltage required

to drive point-of-load (non-isolated) converters in intermediate

bus architectures.
