The Power Management Integrated Circuits (PMIC) are configurable multi-channel devices allow you to scale your power solutions. The PMIC handles the sequencing, voltage and current requirements of processors, Microcontrollers, FPGAs and system-level peripherals.
A PMIC integrates multiple DC-DC converters in one package. It simplifies the power design by reducing component count, while maintaining high-power efficiency and performance.
