Synchronous rectifier control circuit

Abstract:

A synchronous rectifier control circuit includes a drain voltage input, a first gate voltage output, a second gate voltage output, a gate voltage generation circuit, and a trigger control circuit. The gate voltage generation circuit includes a first input coupled to the drain voltage input, and an output coupled to the first gate voltage output. The trigger control circuit includes a first input coupled to the first gate voltage output, a second input coupled to the second gate voltage output, and an output coupled to a second input of the gate voltage generation circuit.
