Description

The BRA20W Series are isolated 20W DC/DC converters.

Designed with highly efficiency, 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.

Applications

These converters are well suitable for battery operated

equipment,

measurement

equipment,

telecom,

wireless

network, Industry control system, everywhere where isolated,

tightly regulated voltages and compact size are required.
