75W Single Output DC-DC converters, 1/4 Brick
The 75W Quarter-brick footprint PYQ series of isolated DC-DC converters operate from an ultra wide range input of 9 to 75Vdc (8:1) with single
output voltages from 12V to 48V. The output voltage can be adjusted between -20% to +15% by using the trim terminal. Sense lines for the output
voltage ensure a stable output voltage even with changing loads. The PYQ75 models have efficiencies of up to 90% and can operate in ambient
temperature of -40 to 105°C. The input to output isolation is 3,000Vac and the units are potted to provide a high resistance to shock and vibration.
The converters are certified according to the 62368-1 safety standards and with additional circuits, the PYQ75 series is also tested according to the
EN 50155 railroad standard for electronic equipment in railroad vehicles.
