DESCRIPTION
The BR300-12S 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 12V and the maximum output current of 25A.
