Description

Shielded Metal Case with Insulated Baseplate

Lead Free Design, RoHS Compliant

6 pin DIP Package with Industry-Standard Footprint

Standard 2”X1” Package

The BUB15W Series are isolated 15W 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.

Customer Design Available

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.

Technical Specification All specifications are typical at nominal input, full load and 25°C unless otherwise stated.
