Abstract:
A voltage regulator includes an adjuster to provide an adjust signal according to its load current to adjust at least one of the feedback signal, the reference signal, the error signal, and the ripple signal of the voltage regulator, to automatically adjust the output voltage. The output voltage increases when the load current increases, and decreases when the load current decreases. Preferably, a CCR voltage regulator according to the present invention will have its PWM frequency varying with its output voltage and thus have better transient performance.
