DC/DC Converters
TEN 20WI Series, 20 Watt
The TEN 20WI series is a family of high performance 20W DC/DC converter mod-
ules featuring ultra wide 4:1 input voltage ranges in a compact 2“ x 1.6“ low profile
package with industry-standard footprint. A very high efficiency allows an operat-
ing temperature range of –40°C to 85°C. A built-in EMI input filter complies with
EN 55022, class A. Further standard features include remote On/Off, output volt-
age trimming, over voltage protection and short-circuit protection.
Typical applications for these converters are battery operated equipment and dis-
tributed power architectures in communication and industrial electronics, every-
where where isolated, tightly regulated voltages are required.
