Abstract
A voltage converting apparatus includes a first comparator, a second comparator, a constant on-time signal generator, a driving stage circuit, an inductor and a reference signal generator. The first comparator compares a feedback signal and a first reference signal to generate a first comparison result. The second comparator compares the first comparison result with a second reference signal to generate a second comparison result. The constant on-time signal generator generates a constant on-time signal. The reference signal generator generates the second reference signal with reducing voltage during a first time period according to an input voltage or a driving signal, and generates the second reference signal with rising voltage during a second time period according to a preset slope. The reference signal generator sets the first time period and the second time period according to the constant on-time signal.
