ROHM BD71847AMWV-E2

BD71847AMWV is a programmable Power Management IC (PMIC) for powering single-core, dual-core, and quad-core SoC’s such as NXP-i.MX 8M Mini. It is optimized for low BOM cost and compact solution footprint. It integrates 6 Buck regulators and 6 LDO’s to provide all the power rails required by the SoC and the commonly used peripherals. QFN package and pinout support low cost Type 3 (non-HDI) PCB. Programmable power sequencing and output voltages, flexible power state control for easier system design and supports a wide variety of processors and system implementations.
