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 1):
A power converter comprising:\n a primary side having a primary winding operatively coupled to an input power source by a power switch; a secondary side having a secondary winding magnetically coupled to the primary winding and electrically coupled to an output configured for connection to a load; an auxiliary winding magnetically coupled to the secondary winding and operatively coupled to a controller configured to operate the power switch responsive to a reflected output voltage sensed via the auxiliary winding to alternately close, thereby storing energy from the input power source in the primary winding, and open, thereby delivering energy from the secondary winding to the output, wherein the controller is further configured to:\n operate in a voltage regulation mode, in which peak current through the primary winding is controlled to maintain an output voltage of the converter at its regulation setpoint, when a voltage error signal corresponding to a difference between the output voltage and a voltage regulation setpoint of the power converter exceeds a first threshold; and \n transition to an energy regulation mode, in which minimum peak current through the primary winding is maintained to deliver a fixed amount of energy to the output, when the voltage error signal of the power converter falls below the first threshold.
