TDK-Lambda PYQ50 30W to 50W Single Output DC-DC Converters

TDK-Lambda PYQ50 30W to 50W Single Output DC-DC Converters are quarter-brick footprint, isolated DC-DC converters that operate from an ultra-wide input range of 14V_DC to 160V_DC (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. Output voltage sense lines ensure a stable output voltage even with changing loads. The PYQ50 models feature efficiencies of up to 89%, 3,000VDC I/O isolation, and operate in an ambient temperature range of -40°C to +100°C. The units are potted to provide a high resistance to shock and vibration. Certified according to the 62368-1 safety standards and with additional circuits, the PYQ50 components are also tested according to the EN 50155 railroad standard for electronic equipment in railroad vehicles.
