Patent ID: 7888925

Claim:
A method of operating a synchronous power converter, the method comprising: generating a control signal in a load current compensation circuit coupled to a synchronous power converter based on a light load condition at the synchronous power converter, the control signal operable to control a gate driver for at least one power switch of the synchronous power converter; and when the gate driver is turned off via the control signal of the load current compensation circuit, monitoring one or more comparison signals in a reference voltage adjustment module of the load current compensation circuit, a first comparison signal of the one or more comparison signals indicative of a voltage level at a phase node of the synchronous power converter, and based on a remaining body diode conduction level associated with a body diode for the at least one power switch as detected by at least a second comparison signal of the one or more comparison signals, adjusting a reference voltage for the at least one power switch with the reference voltage adjustment module until the body diode is no longer conducting.
