TDK-Lambda PYD20 20W Single- & Dual-Output DC-DC Converters

TDK-Lambda PYD20 Single- and Dual-Output DC-DC Converters are 20W 2" x 1" footprint isolated DC-DC converters. The TDK-Lambda PYD20 DC-DC Converters operate from an ultra-wide range input of 8.5VDC to 160VDC (18:1) with single- and dual-output voltages from 5V to 48V. Single-output models can be adjusted from -20% to +15% using the trim terminal. PYD20 models have up to 90% efficiencies and can operate in an ambient temperature range of -40°C to +105°C. The input-to-output isolation is 3000VAC, and the units are potted to provide a high resistance to shock and vibration. The converters are certified according to 62368-1 safety standards, and with additional circuits, the PYD20 series is also tested according to the EN 50155 railroad standard for electronic equipment in railroad vehicles.
