Abstract:
A ripple regulator for providing a pulse width modulation (PWM) signal for regulating an output voltage of a power converter switching stage. The regulator including a ripple circuit for providing a ripple voltage; a comparison circuit for comparing the ripple voltage to an output of an error amplifier; and a PWM circuit producing the PWM signal and receiving an output of the comparison circuit and a clock signal input, the clock signal input determining a first edge of the PWM signal and the output of said comparison circuit determining a second edge of the PWM signal.
