Isolation DC Bus Converter
The BusQor^™ BQ55120ETL16 bus converter is a next-gener-
ation, 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 BusQor
series provides an isolated step down voltage from 35-55V to
a 12V intermediate bus with no regulation in a standard
“eighth-brick” module. BusQor converters are ideal for creat-
ing the mid-bus voltage required to drive point-of-load (non-iso-
lated) converters in intermediate bus architectures. RoHS com-
pliant (see page 12).

Operational Features
• Ultra-high efficiency, >95% at full rated load current
• Delivers up to 16 amps of output current (192W) with
minimal derating - no heatsink required
• Input voltage range: 35V – 55V provides 12V bus for
distributed power architectures
• Fixed frequency switching provides predictable EMI per-
formance
Mechanical Features
• Industry standard eighth-brick bus converter pin-out
• Industry standard size: 0.90” x 2.3” (22.9x58.4mm)
• Total height only 0.320” (8.13mm), permits better air-
flow and smaller card pitch
