Introduction to PMIC-LED Drivers

Power Management IC (PMICs) are integrated circuits that help regulate, manage and control the voltage and current of different devices. They are most commonly used to power, monitor, and optimize lithium ion, nickel-metal hybrid, and other battery-powered electronic systems. In the world of LEDs, PMICs have become incredibly important. They can be used to control power, monitor and optimize the brightness of LEDs while maintaining efficiency. PMIC-LED Drivers are a specialized version of these PMICs, designed to provide power and control to LEDs.
