20W Single and Dual Output DC-DC converters

The 20W 2 x 1” footprint PYD series of isolated DC-DC converters operate from an ultra wide range input of 8.5 to 160Vdc (18:1) with single and

dual output voltages from 5V to 48V⁽¹⁾. Single output models can be adjusted -20% to +15% by using the trim terminal. The PYD20 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 PYD20 series is also tested according to the EN 50155 railroad standard for electronic equipment in railroad vehicles.

Notes

(1) ±12V dual output models can provide a 24V single output by utilizing just the +Vout and -Vout pins, leaving the COM unconnected. Similarly ±15V models

can be used as a 30V single output and ±24V models a single 48V output.
