DC/DC Converter
R-78HB-0.5(L)
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 8:1 is unsurpassed by any other converter and allows the full stored
energy utilization 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 replacement 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.

Short Circuit Protection (SCP)
Short Circuit Input Current
Optional Diode Protection Circuit
Add a blocking diode to Vout if
current can flow backwards into
the output, as this can damage the
converter when it is powered down.
The diode can either be fitted
across the device if the source is
low impedance or fitted in series
with the output (recommended).
