TMR 2WIN Series, 2 Watt
Compact SIP-8 package
Temperature range –40 to +90°C (up to
+75°C at full load)
Excellent load and line regulation
Continuouse short-circuit protection
Overload protection
I/O isolation 1500 VDC
Remote On/Off control
3-year product warranty
UL 62368-1 IEC 62368-1
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
compact 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 architectures in communication, instrumentation and industrial
electronics, everywhere where space on the PCB is critical.
