BD71847AMWV Platform Design Guide

PublishTime：2021-10-15

BD71847AMWV is a Power Management Integrated Circuit (PMIC) available in 56-QFN package and dedicated to the application powered by 5V input. PMIC includes six Buck convertors, six LDOs, one internal load switch and crystal oscillator driver for RTC clock. These functions are designed to support the specific power requirements from NXPi.MX 8M mini platform to achieve the required performance for cost-sensitive applications.
The below figure is the outline of the power map between PMIC and i.MX 8M mini SoC, showing that all voltage rails required by SoC are satisfied.
“BD71847AMWVPlatform Design Guide” provides the guideline for designing PCB including recommendation for the PCB layer stack up, the components placement and the PCB routings.
To reduce the risk that comes from PCB layout or parts placement, the guideline is strongly recommended to be applied to the PCB design.
