Abstract
In one example, a method includes activating, by a controller of a power converter, a switch of the power converter that controls an amount of energy provided by the power converter; receiving, by an input of the controller, a signal that represents an amount of current flowing through the switch; responsive to determining that the amount of current flowing through the switch is greater than or equal to a threshold amount of current, deactivating, by the controller, the switch; and responsive to determining that an amount of time elapsed since activation of the switch is greater than a threshold amount of time, deactivating, by the controller, the switch.
