Wiki Reference

Power management integrated circuits, also known as power management ICs or PMICs, are integrated circuits designed for the purpose of power management. They typically include multiple DC/DC converters or their control components. PMICs are commonly found in battery-operated devices (such as mobile phones and portable media players) as well as embedded devices (such as routers) to reduce the amount of space needed for power management.
