DC/DC Converter
R-78HE-0.3
Description
The R-78HE-5.0-0.3 is a low cost switching regulator module in a compact SIP3 package that has been
specially designed for battery-powered use, but will find many other high input voltage applications.
The exceptionally wide input voltage and operating temperature range, high MTBF (15 mio. hrs),
tight regulation and low quiescent current consumption makes this converter ideal for 36V/48V
lithium-ion and 12V/24V/48V lead-acid battery-powered applications. The 100V surge withstand
capability means that external voltage clamping circuits can be eliminated and only a simple LC filter is
needed for Class A and B EMC conformity.
