A device and method for controlling a power supply. The method includes: a first correction signal is generated according to a down-slope waveform and a second correction signal is generated according to an up-slope waveform, in a period of the switching element. Therefore, two kinds of corrections can be performed by using an oscillator, while the area of the circuit can be reduced and the cost of the integrated circuit can be decreased.

Device and method for controlling power supply with correction behaviour in a power circuit

A device and method for controlling a power supply. The method includes: monitoring a feedback signal of a feedback terminal; determining whether the feedback signal of the feedback terminal is not a pulse signal; and terminating an on/off operation of a switching element when the feedback signal of the feedback terminal is not a pulse signal. Therefore, an abnormal status of the device can be correctly detected with a simple structure when the feedback terminal is open or is shorted with other terminals, while an error operation and a damage of the device can be avoided.
