Title:
POWER MANAGEMENT INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/021695
Kind Code:
A1
Abstract:
Disclosed in the present application is a power management integrated circuit, comprising: an I2C interface circuit, which is connected to a logic pin of the integrated circuit and is used for communicating with an external main controller, so as to transfer an adjustment parameter set by the main controller; and a driving circuit, which is used for converting a switching signal into a driving signal and applying same to a control end of a power switch in the power management integrated circuit, and adjusting electric energy transfer from an input end to an output end of the power management integrated circuit by controlling the turning-on and turning-off of the power switch, so as to provide a stable output voltage, the switching signal being obtained on the basis of the adjustment parameter, wherein the driving rate of the driving circuit and/or the power supply voltage of the I2C interface circuit can be adjusted, such that when interference occurs in the communication of an I2C interface, the communication accuracy of the integrated circuit can be increased by adjusting the driving rate of the driving circuit and/or the power supply voltage of the I2C interface circuit.
