15DMW4_S & 15DMW4_D Series
15W - Single/Dual Output - Wide Input - Isolated & Regulated
1“ x 1“ DC-DC Converter
DC-DC Converter
15 Watt
The 15DMW4_S & 15DMW4_D series are isolated 15W DC/DC conver-
ters. 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 protection and over voltage protection.
