TDK-Lambda PYQ75 75W Single-Output DC-DC Converters
TDK-Lambda PYQ75 75W Single-Output DC-DC Converters are quarter-brick, isolated devices that operate from an ultra-wide input range of 9VDC 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. Output voltage sense lines ensure a stable output voltage even with changing loads. The PYQ75 models feature 90% efficiency, 3000VAC I/O isolation, and an ambient temperature range of -40°C to +105°C. The units are potted to provide a high resistance to shock and vibration. TDK-Lambda PYQ75 75W Single-Output DC-DC Converters are certified according to the 62368-1 safety standards, and with additional circuits, they are also tested according to the EN 50155 railroad standard for electronic equipment in railroad vehicles.
