ABSTRACT:
A switching power supply comprising a transformer (10) the secondary side of which communicates a feedback signal to a current limiter (35). The current limiter (35) consists essentially of resistor and diode elements (28, 32) and is operative in response to the feedback signal and a reference voltage signal received from a pulse-width modulator (26) to prevent or permit current flow through the diode (32).
