Abstract

Disclosed are a power supply circuit and its electronic equipment. The power supply circuit includes a memory for storing external configuration data, and the configuration data includes at least one amplitude parameter; a register for reading configuration data and setting a registered value according to at least one amplitude parameter; a timer for using The register reads at least part of the amplitude parameters in the configuration data every set time; the digital-to-analog converter is connected to the register to output a corresponding voltage signal according to the registered value, wherein, in the AC mode, the power supply circuit provides Voltage signal in AC form. The power supply circuit of the present invention sets the value in the register through the configuration data in the memory, without real-time acquisition of externally provided configuration data, improves the stability of the power supply circuit, and reduces the integration complexity of the power supply circuit.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply circuit and electronic equipment thereof. Background technique [0002] As the functions of electronic devices become more and more complex, the requirements for power supply chips used to supply power to back-end circuits in electronic devices are getting higher and higher. General electronic equipment requires a power supply chip to provide AC voltage and DC voltage. [0003] The existing power supply chip generates the DC voltage and AC voltage required by the back-end circuit of the electronic equipment through real-time control and updating of digital signals. However, the above-mentioned power supply chip needs to integrate at least a micro-control chip, a digital signal chip, and an operational amplifier. The circuit of the power supply chip is complex and expensive, and the integration is unstable, which may have potential risks. [0004] Therefore, ...
