Abstract
A circuit for controlling a switch in a power converter in which peak current is regulated to achieve a specified average current through a load. Control logic is operable to monitor a voltage across a sensing resistor such that when the voltage across the sensing resistor reaches or exceeds a threshold value, the control logic generates a signal that causes a switch to be turned OFF.
