Abstract
In a flyback converter receiving a high voltage DC input for generating a low voltage output, a power control circuit includes a peak current mode controller having as an input, the flyback converter output. The controller generates a feedback signal to the flyback converter for controlling the switching frequency of switches present in the flyback converter. The peak current controller includes a clock circuit. Circuitry monitors the high voltage DC input. The monitoring circuit generates a control signal which is applied to the controller clock circuit for controlling the switching frequency of the flyback converter to thereby control output power levels.
