Abstract
A switching regulator includes a capacitor, a charge control circuit, a discharge detector, a switch circuit, and a feedback circuit. The charge control circuit charges and discharges the capacitor. The discharge detector has an input coupled to the capacitor to detect when the capacitor has discharged to a predetermined level to indicate an over-current condition. The switch circuit is coupled to receive an input voltage. The switch circuit is made conductive and non conductive by a switching signal for supplying an output voltage at a regulated voltage level. The duty cycle of the switching signal is reduced in response to an indication of an over-current condition. The feedback circuit is for controlling a discharge rate of the capacitor.
