With features including four DC/DC buck converters, a boost DC/DC converter, and six low-dropout regulators (LDOs), the STMicroelectronics STPMIC1 power-management IC (PMIC) satisfies the complex power demands of highly integrated application-processor based systems.

The chip is optimized as a companion PMIC for ST’s STM32MP1 heterogeneous multicore microprocessors, which target a broad range of applications by integrating single or dual Arm® Cortex®-A7 and Cortex-M4 cores, an optional 3D graphics processing unit, and rich digital and analog peripherals.

More than simply saving board space and BOM cost, compared to arranging the same number of power rails using discrete components, the STPMIC1 also provides power-rail monitoring and protection, handles power-up/down sequencing, and meets the ST32MP1 accuracy and settling-time specifications (more info).
