ABSTRACT:
An integrated circuit controller for a switching power converter implementing feed-forward and synchronization features. The controller IC has pins which permit dual functionality. The feed-forward feature is implemented with a supply voltage from an unregulated auxiliary winding which additionally powers the controller. The synchronization feature is implemented by coupling an external synchronization signal to a feedback pin of the controller IC to which a feedback signal from the output of the converter is also coupled.
