Power management integrated circuit

Although PMIC refers to a wide range of chips (or modules in system-on-a-chip devices), most include several DC/DC converters or their control part.

The term PMIC refers to a class of integrated circuits that perform various functions related to power requirements.

By incorporating these functions into one IC, a number of improvements to the overall design can be made such as better conversion efficiency, smaller solution size, and better heat dissipation.

[2] A PMIC may include battery management, voltage regulation, and charging functions.

Some models feature a low-dropout regulator (LDO), and a real-time clock (RTC) co-operating with a backup battery.
