Abstract
A synchronous rectifier control circuit includes a drain voltage input, a gate voltage output, a gate voltage generation circuit, a burst detection circuit, an on-time monitor circuit, and a burst mode reset circuit. The gate voltage generation circuit includes a first input coupled to the drain voltage input, and an output coupled to the gate voltage output. The burst detection circuit includes a first input coupled to the drain voltage input, and an output coupled to a second input of the gate voltage generation circuit. The on-time monitor circuit includes an input coupled to the output of the gate voltage generation circuit. The burst mode reset circuit includes a first input coupled to the drain voltage input, a second input coupled to an output of the on-time monitor circuit, and an output coupled to a second input of the burst detection circuit.
