Abstract
A circuit for controlling a power converter includes an SR switching device, a light load detection circuit generating a load detection signal in response to a conduction signal and an operation mode signal, and an SR driver generating a control signal having a value according to the load detection signal and provide the control signal to the SR switching device. A method of controlling a power converter includes generating a load detection signal in response to a conduction signal and an operation mode signal and generating a control signal having a value according to the load detection signal. The control signal has a first value when the load detection signal is asserted and has a second value when the load detection signal is de-asserted.
