DESCRIPTION
The BR400 is an isolated DC-DC converter that uses an industry nonstandard
quarter-brick structure and features high efficiency and power density.
It provides 12 V outputs and supports the maximum output current of 33 A.
Two BR400s can be connected in parallel to provide the maximum output
current of 54 A.
The BR400 communicates over PMBus 1.1 to support monitoring and alarm
reporting functions, such as monitoring the output voltage and current, input
voltage, digitally adjusting the voltage, and activating software.
