Abstract
A voltage converting apparatus includes a comparison circuit, a compensation signal generator, and a voltage converter. The comparison circuit generates a comparison result according to an output voltage, an input voltage, and a compensated feedback signal. The compensation signal generator provides a compensation signal held to be equal to a reference voltage at a first time interval in an enable period in a working cycle and sets the compensation signal to be a ramp signal at a second time interval in the enable period. The compensation signal generator generates the compensated feedback signal according to a feedback signal and the compensation signal. The voltage converter generates a control signal according to the comparison result, performs a voltage converting operation through an inductor according to the control signal, and generates the output voltage. The feedback signal is generated according to a current on the inductor.
