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 pack-
age.
An excellent efficiency up to 84% allows –40°C to +85°C operation tempera-
tures at full load. Further features include remote On/Off control and continu-
ous short circuit protection. Typical applications for these ultra-compact con-
verters are battery operated equipment and distributed power architectures in
communication, instrumentation and industrial electronics, everywhere where
space on the PCB is critical.
