PF3001 Functional Internal Block Diagram
Analog Solutions—Robust Reliable Performance
PF3001
PF Series 10-Channel Configurable PMIC
Overview
The PF3001 power management integrated circuit (PMIC) features a configurable architecture
that supports numerous outputs with various current ratings as well as programmable voltage
and predefined sequencing. This enables the PF3001 to power the core processor, external
memory and peripherals to provide a single-chip system power solution in multiple applications,
reducing design complexity and lowering overall bill of materials. In consumer and industrial
environments the high-performance architecture offers a cost optimized solution for “always
ON” applications while PF3000 enables Low Power implementation.
The PF3001 is ideally suited for i.MX 6UL applications processors, and can also meet the
power consumption requirements for other low end i.MX 6 series, including the i.MX 6Solo,
i.MX 6SoloLite, i.MX 6SoloX and i.MX 7 series. The pin to pin compatibility with the PF3000
makes the i.MX and PF3000/1 solution scalable and allows to reuse the current Board Support
Package (BSP) used in multiple reference designs. This provides customers with a platform-
level solution from a single supplier to enable faster time to market and reduces
engineering effort.
