Features
Switching Regulator
Designed for 12V - 60V battery-powered apps Wide input range (6.5V - 72V) 100V surge withstand -40°C to +105°C operation at 48V input, full load Short circuit protected Efficiency up to 83%, no need for heatsinks
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.
