The BR120 series is a new generation isolated DC-DC converter that uses an
industry standard quarter-brick structure, and features high efficiency and
power density, operates from an input voltage range of 36 V to 75 V,
provides the rated output voltage of 5V / 12V and the maximum output current
of 20A / 10A.
