TRACOPOWER TMR2

DC/DC Converters
TMR 2E Series, 2 Watt
Features
◆ Wide 2:1 input voltage range
◆ Compact SIP-8 package
◆ Cost optimized design
◆ Temperature range –40° to +85°C
◆ I/O isolation 1000VDC
◆ Remote On/Off control

The TMR-2E series is a family of isolated 2W dc-dc converter modules with regulated output, featuring wide 2:1 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° to +85°C operation temperature. Further features include remote On/Off control and continuous short circuit protection. The
compact dimensions and cost optimise design make this converters an ideal solution for applications in communication equipment, instrumentation and industrial
electronics.
