Abstract:
An exemplary switching regulator, is provided. The switching regulator includes an oscillator, a PWM logic controller, an inductor, a capacitor, a switch, a driver, a current sense amplifier, and a minimum power pulse width generator. The current sense amplifier and the minimum power pulse width generator compose a first feedback loop for generating a first feedback signal to the PWM logic controller.
