Power Management Integrated Circuits are chips that take on the responsibility of transforming, distributing, detecting, and managing electrical energy in electronic device systems. They are mainly responsible for identifying the amplitude of CPU power supply, generating corresponding short moment waves, and driving the subsequent electrical circuits to output power. Common power management chips include LMG3410R050 [1], UCC12050, BQ25790 [2], HIP6301, IS6537, RT9237, ADP3168, KA7500, TL494, etc.

Power management integrated circuits (power management ICs or PMICs or PMU as unit) are integrated circuits for power management. Although PMIC refers to a wide range of chips (or modules in system-on-a-chip devices), most include several DC/DC converters or their control part. A PMIC is often included in battery-operated devices (such as mobile phone, portable media players) and embedded devices (such as routers) to decrease the amount of space required.

The scope of power management is relatively broad, including power conversion (DC-DC, AC-DC, and DC-AC), power distribution and detection, as well as systems that combine power conversion and power management. Correspondingly, the classification of power management chips also includes these aspects, such as linear power chips, voltage reference chips, switch power chips, LCD driver chips, LED driver chips, voltage detection chips, battery charging management chips, gate drivers, load switches, broadband gap switches, etc.
