Features

◆ Wide 4:1 input voltage range

◆ Compact SIP-8 package

◆ Cost optimized design

◆ Temperature range –40°C to +85°C

◆ I/O isolation 1500 VDC

◆ Remote On/Off control

◆ 3-year product warranty

The TMR-3WIE series is a family of isolated 3 W dc-dc converter modules with

regulated output, featuring wide 4:1 input voltage ranges. The product comes in

a compact SIP-8 plastic package with small footprint occupying only 2.0 cm2 (0.3

square in.) of board space.

An excellent efﬁciency allows –40°C to +85°C operation temperature. Further fea-

tures include remote On/Off control and continuous short circuit protection. The

compact dimensions and cost optimized design make this converters an ideal solu-

tion for applications in communication equipment, instrumentation and industrial

electronics.
