20DMW_1.5 Series
20W - Single/Dual Output - Ultra Wide Input - Isolated & Regulated
DC-DC Converter
DC-DC Converter
20 Watt
The 20DMW_S & 20DMW_D series are isolated 20W DC/DC converters.
Designed with high efficiency, they allow the operating temperature ran-
ge 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
2 : 1 input voltage range, remote on/off control, trimmable output, short-
circuit protection and over voltage protection.
Wide 2:1 input voltage range
High efficiency up to 90%
Remote On/Off
Input/output isolation voltage:
1.5K Vdc
Short circuit protection (SCP)
RoHS compliant
Operating temperature range:
-40°C to +85°C
Over voltage protection:

Shielded metal case with
insulated baseplate
20W DIL PACKAGE
These converters are well suitable for battery operated equipment, mea-
surement equipment, telecom, wireless network, Industry control sys-
tem, everywhere where isolated, tightly regulated voltages and compact
size are required.
