Abstract
A power supply module to power the control circuit of a switching mode power supply is provided. Based on the determination of whether the switching mode power supply is under a light or open load condition, the power supply module can dynamically provide the power to the control circuit of the switching mode power supply. Therefore, the performance of the power supply can be increased and the power loss can be decreased when the switching mode power supply is under a light or open load.
