The TMR 3 series is a new family of isolated 3 W 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 a small footprint occupying only
2.0 cm² (0.3 square inch) of board space. An excellent efficiency allows –40°
to +85°C operation temperatures. Further features include remote On/Off con-
trol and continuous short circuit protection. The compact dimensions of these
converters make them an ideal solution for many space critical applications in
communication equipment, instrumentation and industrial electronics.
