30-50W Single Output DC-DC converters, 1/4 Brick
The 30-50W Quarter-brick footprint PYQ series of isolated DC-DC converters operate from an ultra wide range input of 14 to 160Vdc (12:1) with
single output voltages from 5V to 48V. The output voltage can be adjusted between -20% to +10% by using the trim terminal. Sense lines for the
output voltage ensure a stable output voltage even with changing loads. The PYQ50 models have efficiencies of up to 89% and can operate in
ambient temperature of -40 to 100°C. The input to output isolation is 3,000Vdc 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 PYQ50 series is also tested
according to the EN 50155 railroad standard for electronic equipment in railroad vehicles.
