Description
The R-78HBxx-Series high efficiency, high input voltage switching regulators are ideally suited to replace
78xx linear regulators and are pin compatible. The efficiency of up to 96% means that very little energy is
wasted as heat so there is no need for any heat sinks with their additional space and mounting costs.
An input voltage range of up to 8:1is unsurpassed by any other converter and allows the full stored energy
utilisation of standard and high voltage batteries. The fully protected output is ideal for industrial applications
(especially for industry standard 24VDC bus supplies) and the L-Version with 90° pins allows direct replace-
ment for laid-flat regulators where component height is at a premium. Low ripple and noise figures and a
short circuit input current of typically only 15mA round off the specifications of this versatile converter
series.
Typical applications include telecommunication, automotive, industrial, aerospace and battery powered
applications.
