The GDQ75S12B-4Q is a new generation
isolated DC-DC converter that uses an
industry standard quarter-brick structure,
featuring high efficiency and power density
with low output ripple and noise. It
operates from an input voltage range of 36
V to 75 V, and provides the rated output
voltage of 12 V as well as the maximum
output current of 75 A.
