Abstract:
A charging path is provided for the charging of an bootstrap capacitor that stores a driver power supply voltage for driving an active clamp switch transistor in a flyback converter. The charging path couples charge from an active clamp capacitor to charge the bootstrap capacitor.

Claim (Index 17):
A method of operation for a flyback converter, comprising:\n charging a power supply capacitor to provide a power supply voltage to a controller for the flyback converter; conducting charge from the power supply capacitor through a diode path to charge a bootstrap capacitor to provide a driver power supply voltage for driving an active clamp switch transistor; switching on a charging transistor responsive to the power supply voltage being less than a threshold voltage to conduct charge from a positive plate of an active clamp capacitor through the charging transistor to charge the bootstrap capacitor; and switching off the charging transistor responsive to the power supply voltage being greater than the threshold voltage.
