A typical PMIC includes one or more switching DC-to-DC converters, such as buck and boost converters, along with linear regulators like Low Dropout Regulators (LDOs). At the core of a PMIC is the power transistor, a large transistor occupying several square millimeters and designed as multiple banks of transistors. These parallel devices must have very low resistance (RdsON) to minimize power loss and heat, thereby improving power conversion efficiency.
Convert and regulate the input power to various levels required by different components of a device. This includes step-down (buck) converters, step-up (boost) converters, and linear regulators.
They can distribute the correct amount of power to each subsystem within a device, ensuring that all parts function correctly without overloading.
Managing the order in which different components are powered on and off to ensure stable operation and to protect sensitive components from damage due to improper power sequencing.
For battery-powered devices, PMICs are crucial in managing charging, discharging, and monitoring battery health to ensure longevity and safety.
Optimizing power consumption by implementing techniques such as dynamic voltage scaling and sleep modes to reduce energy use when full power is not required.
PMICs include various protection features such as over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), and thermal shutdown to safeguard the device and its components from damage due to electrical faults or overheating.
Linear Regulators (LDOs) Provide a simple solution for voltage regulation with low noise and fast transient response but are less efficient compared to switching regulators. Different with LDOs, switching regulator include buck converters, boost converters, and buck-boost converters, which offer higher efficiency by converting power using high-frequency switching.

What Are Power Management ICs?
Power Management Integrated Circuits (short for PMIC) 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. Common power management chips include LMG3410R050, UCC12050, BQ25790, HIP6301, IS6537, RT9237, ADP3168, KA7500, TL494 and so on.A typical PMIC includes one or more switching DC-to-DC converters, such as buck and boost converters, along with linear regulators like Low Dropout Regulators (LDOs). At the core of a PMIC is the power transistor, a large transistor occupying several square millimeters and designed as multiple banks of transistors.
