At first, the power consumption of the phone is very fast, and there will be leakage after serious, and finally the phone will not be able to turn on. A broken power management chip will also affect the voltage of the cpu, resulting in cpu damage. Power Management Integrated Circuits (Power Management Integrated Circuits) is a chip that is responsible for the transformation, distribution, detection and other power management duties in an electronic device system. It is mainly responsible for identifying the CPU power supply amplitude, generating the corresponding short moment wave, and promoting the power output of the back-end circuit.
Commonly used power management chips are HIP6301, IS6537, RT9237, ADP3168, KA7500, TL494 and so on.
The main power management chips are dual-in-line chips, and some are surface-mount packages, among which HIP630x series chips are more classic power management chips, designed by the famous chip design company Intersil.
It supports two\/three\/four phase power supply, support VRM9.0 specification, voltage output range is 1.1V-1.85V, can adjust the output for 0.025V interval, switching frequency up to 80KHz, with large power supply, small ripple, small internal resistance and other characteristics, can precisely adjust the CPU power supply voltage.

If the power management chip of the mobile phone is broken, it will not be able to charge, the amplifier will not work, and the other party will not hear you
