ABSTRACT:
A power supply controller (25) is configured to accurately adjust the value of an output voltage of a power supply system (10) responsively to the output voltage increasing to an undesirable value. The controller (25) accurately limits an upper value of the output voltage during a light load condition, and rapidly reduces the value of the output voltage to a desired value. The power supply controller is configured to turn off the first output transistor but inhibit turning off the second output transistor using two different control signals.
