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 +85°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.
