The power management chip requires a burn program. In the power management chip, there are some important control logic that needs to be programmed to achieve specific functions. These programs are often referred to as \"firmware\" or \"code\" and are loaded into the chip via a programmer or emulator.
These programs control the output voltage, current and other parameters of the power management chip to ensure the safe and efficient operation of the equipment. Therefore, the burning procedure is a necessary step for the power management chip to work properly.
Can not be generalized, some need such as computer ec, some do not need.
