The TMR 3WI series is a new family of isolated 3W DC/DC converters with reg-
ulated output, featuring ultra-wide 4:1 input voltage range. The product comes
in a ultra-compact SIP plastic package with a small footprint occupying only 2.0
cm² (0.3 square inch) 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 very compact dimensions of these converters make them an
ideal solution for many space critical applications in battery-powered equip-
ment and instrumentation.
