The scope of power management is relatively wide, including power conversion (DC-DC, AC-DC and DC-AC), power distribution and detection, and systems that combine power conversion and power management. Accordingly, the classification of power management chips also includes these aspects, such as linear power chips, voltage reference chips, switching power chips, LCD driver chips, LED driver chips, voltage detection chips, battery charging management chips, gate drivers, load switches, wide band gap switches and so on. A chip that is responsible for the transformation, distribution, detection and other power management of electric energy in the electronic equipment system. It is mainly responsible for identifying the power supply amplitude of CPU, generating corresponding short moment waves, and pushing the latter circuit to output power. Commonly used power management chips are LMG3410R050, UCC12050, BQ25790, HIP6301, IS6537, RT9237, ADP3168, KA7500, TL494, etc.
