Power Management ICs

Power management ICs combine several voltage converters and controllers on one chip. They are integrated circuits whose main task is power management: With the help of these ICs, the power demand of a system can be managed. Both the flow and the direction of the current can be specifically controlled by power management ICs. Power management ICs are found in digital devices such as smartphones and other battery-powered devices. In this context, they are used, for example, for voltage regulation and in the area of charging functions and battery management.
