3-year product warranty The TMR-3E series is a family of isolated 3 W dc-dc converter modules with regu-
lated output, featuring wide 2:1 input voltage ranges. The product comes in a com-
pact 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 +8C 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.
