The TMR-2WIN series is a family of isolated 2 W DC/DC converter modules with
accurately regulated output voltages and ultra-wide 4:1 input voltage ranges. They
require no minimum load and are protected against overload and short circuit.
An excellent efficiency along with the use of high grade components allows a com-
pact construction in SIP-8 package; even the converters can reliably operate in
an ambient temperature of –40°C to +75°C at full load and up to 90°C with 50%
power derating. Typical applications for these converters are distributed power ar-
chitectures in communication, instrumentation and industrial electronics, everywhere
where space on the PCB is critical.
