Isolation
The BusQor BQ55090QEx60 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 BusQor
series provides an isolated step down voltage from 48
V to 12 or 9.6 V 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.
