ABSTRACT:
A DC power supply having an input stage receiving input power at one voltage and an output stage connected to the input stage producing output power at another, output voltage. The output stage receives a control signal reducing the output voltage by a prescribed amount when the output current exceeds a given level. The control unit includes a comparator which compares the output current with a reference level and produces a current foldback signal if the output current exceeds the reference level.
