20DMW4_1.5 Series
20W - Single/Dual Output - Ultra Wide Input - Isolated & Regulated
DC-DC Converter
DC-DC Converter
20 Watt
The 20DMW4_1.5 series are isolated 20W DC/DC converters. Designed
with high efficiency, they allow the operating temperature range of these
units to be -40°C to +85°C (with derating) in a 6 pin DIP package with
industry-standard footprint. Further features include wide 4 : 1 input
voltage range, remote on/off control, trimmable output, short-circuit pro-
tection and over voltage protection.
Wide 4:1 input voltage range
High efficiency up to 90%
Remote On/Off
Input/output isolation voltage:
