The working principle of the power chip 626pg is that it can convert the input power into a voltage suitable for electronic equipment. This chip usually includes a switching power supply module, which can quickly turn on and off the power supply, thus improving the power supply efficiency. When the power chip 626pg works, it will control the power supply through a series of circuits, and adjust the voltage to ensure the stability of the output power supply. Power management chip is a chip that undertakes the responsibility of power management such as power conversion, distribution and detection in electronic equipment system. It is mainly responsible for identifying the power supply amplitude of CPU, generating corresponding short moment wave and promoting the output power of the latter circuit.
