PF3000 Functional Internal Block Diagram
Analog Solutions—Robust Reliable Performance
PF3000
PF Series 12-Channel Configurable PMIC
Overview
The PF3000 power management integrated circuit (PMIC) features a configurable architecture
that supports numerous outputs with various current ratings as well as programmable voltage
and sequencing. This enables the PF3000 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. The high-performance architecture
offers improved efficiency across the complete output range and delivers advanced functionality
for consumer and industrial applications.
The PF3000 is ideally suited for i.MX 7 series application processors. It also meets the
power consumption requirements for all low end i.MX 6 series, including the i.MX 6UltraLite,
i.MX 6Solo, i.MX 6SoloLite, and the i.MX 6SoloX. Our compatibility with i.MX applications
processors is shown in multiple reference designs included within the Board Support Package
(BSP) and facilitates software controlled, dynamic voltage scaling. This provides customers
with a platform-level solution from a single supplier to enable faster time to market and reduce
engineering effort.
