Description

The BOB3H3 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,

remote on/off control, 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.
