ABSTRACT:
A spring modulation is proposed to regulate the output voltage of a voltage regulator. The spring modulation comprises a differential amplifier to generate a pair of voltage signal and current signal varied with the difference between a reference signal and a feedback signal related to the output voltage, and a PWM generator to generate a PWM signal in response to the pair of voltage signal and current signal to regulate the output voltage, in such a manner that, in load transient, the greater the difference between the feedback signal and reference signal is, the greater the on-time duty-cycle of the PWM signal is.
