摘要： A converting controller is provided and comprises a first comparing unit, a second comparing unit, a duty cycle operating unit and a reference voltage supplying unit. The first comparing unit receives a detecting signal representing a state of the load and a first reference signal, and generates a first comparing signal accordingly. The duty cycle operating unit controls power conversion of the converting circuit according to the first comparing signal. The second comparing unit receives the detecting signal and a second reference signal, and generates a second comparing signal accordingly. The reference voltage supplying unit supplies the first reference signal and adjusts a level of the first reference signal in response to the second comparing signal.

摘要： A rectifying device is used to prevent any reverse current in a charge pump circuit. Accordingly, energy stored in the charge pump circuit is prevented from being transmitted back to an input voltage source, or energy stored in a capacitor coupled to an output end is prevented from being transmitted back to the charge pump circuit and the input voltage source. Besides, a current limiting unit coupled to the input voltage source or/and the output end is used to protect devices of the charge pump circuit from being burned out due to an overly large current provided by the input voltage source to the charge pump circuit or/and an overly large current provided by the charge pump circuit to the output end when a short circuit occurs.
