摘要：A controller for increasing efficiency of a power converter includes a

comparison module and a gate signal generation unit. The comparison module is used forgenerating a detection voltage according to a direct current (DC) input voltage of aprimary side of the power converter, and comparing the detection voltage with apredetermined value to generate a comparison result. The gate signal generation unit isused for changing a sink current flowing through a gate pin of the controller according tothe comparison result, wherein the gate pin of the controller is coupled to a powerswitch of the primary side of the power converter.
