The TMR-3WI series is a new family of isolated 3W DC/DC converters with regu-
lated 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 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 protec-
tion. The very compact dimensions of these converters make them an ideal solution
for many space critical applications in battery-powered equipment and instrumen-
tation.
