Methods and apparatus for supplying a load according to various aspects of the present invention operate in conjunction with an output stage and a control system driving the output stage. The control system may include a PWM controller adapted to provide a drive signal to the output stage and an over-current protection circuit. The over-current protection circuit may sense an over-current condition at the load and truncate the drive signal in response to the over-current condition.
