The converter has a built in soft start circuit. Rapidly changing the input voltage
from Vin(min) Vin(max) can bypass this circuit and damage the converter.

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 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.
