Abstract

A method of controlling synchronous rectification transistors in a switching converter includes sensing a drain-to-source voltage across each synchronous rectification transistor each switching half-cycle of the switching converter. An average of the sensed drain-to-source voltage is calculated for each synchronous rectification transistor over N prior switching half-cycles. A load current transient in the switching converter is sensed based on the sensed drain-to-source voltage of each synchronous rectification transistor and the calculated average of the sensed drain-to-source voltage for each synchronous rectification transistor over the N prior switching half-cycles.
