Zusammenfassung:The invention provides a power supply chip. The power supply chip comprises a first sub-chip, a second sub-chip, a transformer and an isolator, the first sub-chip comprises an isolation power supply transmitting module and a driving circuit control module, and the second sub-chip comprises an isolation power supply receiving module and a driving circuit buffer module; the isolated power supply transmitting module is used for converting a first current signal input by the input end of the power supply chip into a second current signal, and inputting a third current signal output after the second current signal is coupled by the transformer into the isolated power supply receiving module, and the third current signal is used for supplying power to the drive circuit buffer module; the drive circuit control module is used for outputting a drive signal based on a first control signal input by the input end of the power supply chip, and inputting the drive signal to the drive circuit buffer module through the isola
