Scheme
The TMR-1 and TMR 1SM series are families of isolated 1 W dc-dc converter mod-
ules with regulated output, featuring wide 2:1 input voltage ranges. These products
come in a compact SIP-6 or SMD package with small footprint occupying only 1.2
cm
2
(0.2 square inch) of board space.
An excellent efficiency allows –40°C to +85°C operation temperature. Further fea-
tures include remote On/Off control (SMD-Version) and continuous short circuit
protection. The compact dimensions and cost optimised design make this converters
an ideal solution for applications in communication equipment, instrumentation and
industrial electronics.
