Description

The BQA3R Series are isolated 3W DC/DC converters. Designed

with highly efficiency, allow the operating temperature range of

these units to be -40°C to +85°C in a 24 pin DIP package with

industry-standard footprint. Further features include wide 2 : 1

input voltage range, 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.
