Isolation DC Bus Converter
The BusQor⢠BQ50120QTA20 bus converter is a next-gen-
eration, board-mountable, isolated, fixed switching frequen-
cy 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 BusQor series provides an isolated step down
voltage from 48V to a 12V intermediate bus with no regu-
lation in a standard âquarter-brickâ module. BusQor con-
verters 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 page 12).

Converter
Operational Features
⢠Ultra-high efficiency, >96% at full rated load current
⢠Delivers up to 20 amps (240 Watts) of output current
(power) with minimal derating - no heatsink required
⢠Input voltage range: 42V â 53V
⢠Fixed frequency switching provides predictable EMI per-
formance
