BD71837AMWV Datasheet | ROHM

Description - BD71837AMWV is a programmable Power Management IC (PMIC) for powering single-core, dual-core, and quad-core So C’s such as NXP-i.MX 8M. It is optimized for low BOM cost and pact solution footprint. It integrates 8 Buck regulators and 7 LDO’s to provide all the power rails required by the So C and the monly 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. Features - 8 Buck Regulators - 2.0 MHz Switching Frequency. (BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK7, and BUCK8). - 1.5MHz Switching Frequency. (BUCK6) - Target Efficiency: 83% to 95%. - Output Current & Voltage.
