Abstract
A controller with a multi-function pin, adapted to control a converting circuit according to a control signal for converting an input voltage into an output voltage, is disclosed. The controller has the multi-function pin, an enable unit, an over-current detecting unit and a logic control unit. The enable unit is coupled to the multi-function pin for receiving an enable signal and activates the controller in response to the enable signal. The over-current detecting is coupled to the multi-function pin and determines an over-current value according to an over-current set resistance coupled between the multi-function pin and a voltage source. The over-current detecting unit generates an over-current protection signal according to the over-current value and a current flowing through the converting circuit. The logic control unit determines whether executing an over-current protection according to the over-current protection signal.
