ABSTRACT:
A switching regulator. A pulse width modulation (PWM) unit comprises an output stage and generates a PWM driving signal to control the output stage, such that an inductor delivers an inductor current signal to the load, and a slope compensation unit outputs a slope compensation signal with a compensation slope proportional to a falling slope of the inductor current signal to the PWM unit according to the inductor current signal.
