Abstract
A method and a system for current limiting using PWM control have been provided. The method includes sensing a load current to produce a control voltage. The control voltage is compared with a reference voltage to produce a detected output signal. Thereafter, the detected output signal is delayed and multiplied with a master PWM signal.
