Abstract:
A flyback converter can include an auxiliary winding magnetically coupled to the secondary (output) for sensing a reflected output voltage. A controller can operate a power switch of the flyback converter in a burst mode to deliver a number of pulses, causing the output voltage to reach a threshold, and thereafter suspend switching for a predetermined time period before delivering a further number of pulses. The delivered number of pulses can be counted, and, responsive to a determination that the count is less than a predetermined minimum number of pulses, the predetermined time period can be increased. Responsive to a determination that the count is greater than a predetermined maximum number of pulses, the predetermined time period can be decreased.

Claim (Index 16):
A method of operating a flyback converter, the flyback converter having a primary side including a primary winding operatively coupled to an input power source by a power switch, a secondary side including a secondary winding magnetically coupled to the primary winding and electrically coupled to an output, and an auxiliary winding magnetically coupled to the secondary winding, the method comprising:\n sensing a reflected output voltage of the flyback converter via the auxiliary winding; responsive to the reflected output voltage, operating the power switch to deliver a number of pulses, thereby causing the reflected output voltage to reach an output voltage high threshold; and suspending switching for a predetermined time period before delivering a further number of pulses; count the number of pulses; and adjusting the predetermined time period responsive to a comparison between the counted number of pulses and at least one predetermined number of pulses.
