SN2012027 is a power management integrated circuit (PMIC) chip produced by Texas Instruments, which is used in the iPhone 15 Pro. It is similar to the TPS65657B0 display PMIC in process.
The specific functions of this chip may include power conversion and regulation, which can convert the input voltage into the appropriate voltage required by different components in the device to ensure their normal operation. It may also have functions such as power management and protection, including over – temperature protection, output short – circuit protection, and input under – voltage/over – voltage protection, to improve the stability and reliability of the power supply system. In addition, it may support some specific power – related features and interfaces to meet the power – supply needs of the iPhone 15 Pro’s various components and functions.
