Power Management ICs (PMICs) are specialized integrated circuits designed to manage power requirements in electronic devices. They regulate voltage and current, ensuring that components receive the appropriate power levels for optimal performance. PMICs are commonly used in smartphones, tablets, and other portable electronics. These ICs can integrate multiple functions, such as voltage regulation, battery management, and power distribution, into a single chip. This integration helps reduce the size and complexity of electronic systems, making them more efficient and reliable. By optimizing power usage, PMICs contribute to longer battery life and improved overall device performance.
