The TMR 2 series is a family of isolated 2W DC/DC converter modules with reg-
ulated output, featuring wide 2:1 input voltage ranges. The product comes in a
compact SIP-8 plastic package with small footprint occupying only 2.0 cm² (0.3
square in.) of board space.
An excellent efficiency allows –40° to +85°C operation temperatures. Further
features include remote On/Off control and continuous short circuit protection.
The ultra-compact dimensions of these converters make them an ideal solution
for many space critical applications in communication equipment, instrumenta-
tion and industrial electronics.
