ABSTRACT:
In one embodiment, a power supply controller of a power supply system uses an algorithm to reduce the number of drive pulses to the output transistors under light load conditions. The algorithm groups the drive pulses to the output transistors into sets and removes some of the drive pulses for each set drive pulses issued by the controller. Each successive set removes additional drive pulses.
