Abstract
A flyback converter includes a transformer and a controller operable for controlling a switch coupled in series with a primary winding of the transformer. The controller is configured to operate in multiple modes including a burst mode and a standby mode. In the burst mode, the controller generates a first plurality of discrete pulse groups to turn on the switch and a duration of each pulse in the first plurality of discrete pulse groups is determined by a first reference signal having a first predetermined voltage. In the standby mode, the controller generates a second plurality of discrete pulse groups to turn on the switch and a duration of each pulse in the second plurality of discrete pulse groups is determined by a second reference signal having a second predetermined voltage which is greater than the first predetermined voltage of the first reference signal.
