DC/DC Converter
R-78E-0.5
Description
The R-78E series is a switching regulator module that has been designed to offer all the advantages of a
switching regulator (high efficiency, wide input range, accurate output voltage regulation) but with a low
cost for production quantities. Due to the R-78E’s high efficiency of up to 95% no heat-sink is required.
The compact TO-220 compatible SIP3 package measures only 11.6 x 8.5 x 10.4mm, so it saves
precious board space.
