Abstract
A voltage converting circuit for converting an input voltage into an output voltage is disclosed. The voltage converting circuit includes a modulation signal generator, a comparator and a logic unit. The modulation signal generator is configured for generating a pulse width modulation (PWM) signal responsive to a feedback signal corresponding to the output voltage and a load coupled thereto. The comparator is configured for comparing the feedback signal with a reference signal to output a comparing signal. The logic unit is configured for performing a logical conjunction of the PWM signal and the comparing signal to generate a control signal for adjusting an input current corresponding to the input voltage to regulate the output voltage. A method for converting an input voltage into an output voltage is also disclosed herein.
