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 3):
The controller circuit of  claim 2 , further comprising:\n a summing circuit to produce a sum signal corresponding to a sum of a voltage of a conduction terminal of the switching device and the offset voltage, and a comparator to assert a turn off signal in response to the sum signal having a value greater than the off threshold voltage, wherein the controller circuit, in response to the assertion of the turn off signal, de-asserts the gate signal to turn off the switching device.
