摘要
The present invention provides methods and systems for a flyback converter arranged with synchronous rectifier MOSFETS in such a manner that they operate with a common source potential while still providing for the use of a stacked output winding. With a common source potential, a single rectifier control voltage can be used to operate the rectifiers for multiple outputs greatly simplifying the control circuit. Advantageously, the present invention maintains the inherent simplicity of the flyback design while enabling designs with well-regulated multiple voltage outputs and the efficiency benefits of synchronous rectification.
