Power Management Integrated Circuits

Power Management Integrated Circuits

Power management integrated circuits (power management ICs or PMICs or PMU as unit) are integrated circuits (or a system block in a system-on-a-chip device) for managing power requirements of the host system. Thus PMIC refers to a wide range of chips, however most include some form of electronic power conversion and/or relevant power control functions. A PMIC is often included in battery-operated devices such as mobile phones and portable media players to decrease the amount of space required.
