Abstract
A circuit for controlling a switching mode power supply having a power switch. The switching mode power supply includes a power switch. The control circuit includes a feedback pulse circuit, and a light load pulse circuit. When the load of the switching mode power supply is above a certain load level, the feedback pulse circuit provides a feedback pulse signal to control the power switch operating at a frequency which increases as a load of the switching mode power supply increases. When the load of the switching mode power supply is under the certain load level, the light load pulse circuit provides a light load pulse signal to control the power switch operating at different switching frequencies wherein the different switching frequencies includes at least two switching frequencies.
