Abstract

The invention discloses a power supply circuit and an electrode device. The power supply circuit includes a memory which is used for storing external configuration data including at least one amplitude parameter, a register which is used for reading configuration data and setting a registering value according to at least one amplitude parameter, a timer used for making the register read at least apart of the amplitude parameters of the configuration data at the set time interval, and a digital analog converter which is connected with the register and is used for outputting a corresponding voltage signal according to the registering value, wherein in an AC mode, a voltage signal in an AC mode is provided by the power supply circuit according to the configuration data. The power supply circuit is advantaged in that the value of the register is set according to the configuration data of the memory, acquiring external configuration data in real time is not needed, stability of the power supply circuit is improved, and integration complexity of the power supply circuit is reduced.

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, ...
