Abstract
A controller for use in a power converter includes a first terminal to provide a turn on signal to initiate turning on of a power switch and a second terminal to provide a turn off signal to initiate turning off the power switch. A detection circuit is coupled to detect a turn off time delay. The turn off time delay is the duration of time between an initiating of a turn off of the power switch by the turn off signal and an actual turn off of the power switch. A control circuit is coupled to control the turn on signal to regulate the turn off delay time to a target time value. The control circuit controls the turn on signal by controlling an amount of charge delivered to turn on the power switch.
