Abstract:
A Synchronous Rectifier (SR) controller circuit includes a dead time evaluation circuit, an offset voltage controller circuit, an off threshold control circuit, and a comparator circuit. The dead time evaluation circuit produces an indication of whether a measured dead time of an SR switching device is less than a target dead time. The offset voltage controller circuit determines an offset count using the indication, an offset voltage using the offset count, and high and low saturation indicators according to the offset count. The off threshold control circuit determines a threshold count using the high and low saturation indicators and an off threshold voltage using the threshold count. The comparator circuit determines whether a measured voltage of the SR switching device is greater than a virtual off threshold voltage, the virtual off threshold voltage corresponding to the off threshold voltage minus the offset voltage.

Claim (Index 6):
The controller circuit of  claim 1 , further comprising:\n an off threshold control circuit to increase an off threshold voltage in response to an offset voltage having a minimum value for two consecutive switching cycles of the switching device, and to decreasing the off threshold voltage in response to the offset voltage having a maximum value for two consecutive switching cycles of the switching device, wherein the virtual off threshold voltage corresponds to a difference between the offset voltage and the off threshold voltage.
