The TMR-2WI series is a new family of isolated 2W dc-dc converter modules with
regulated output, featuring ultra-wide 4:1 input voltage ranges of 9-36 VDC or
18-75 VDC. The product comes in a ultra-compact SIP-9 plastic package.
An excellent efficiency up to 84% allows –40°c to +75°C operation temperatures
at full load. Further features include remote On/Off control and continuous short
circuit protection. Typical applications for these ultra-compact converters are bat-
tery operated equipment and distributed power architectures in communication,
instrumentation and industrial electronics, everywhere where space on the PCB is
critical.
