LM3880MF-1AC/NOPB Application Field And Working Principle

Introduction of PMIC - Power Supply Controllers, Monitors

Power Management Integrated Circuits (PMICs) are used to manage and route power in modern electronic systems. They provide various functions to control and monitor power supply in real-time, and form the basic process blocks of power supply systems. Most of modern electronic systems contain several different types of regulators, controllers, and switches to control and monitor the power distribution. This includes circuits for boosting, bucking, chokes, current sources, converters, controllers, drivers, multiplexers, power monitoring, voltage regulators, and other features. By integrating a combination of these functions into a single die, PMICs can provide a reliable and cost-effective solution for complex power management designs.
