  • Device and method for controlling power supply with correction behaviour in a power circuit
    Patent number: 10396670
    Abstract: 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.
