7-Channel Power Management Integrated Circuit for High Performance Applications, Fit for ASIL B Safety Level

PF7100

Roll over image to zoom in

The PF71 is a power management integrated circuit (PMIC) designed for high performance i.MX 8 processors. It features five high efficiency buck converters and two linear regulators for powering the processor, memory and miscellaneous peripherals.

Built-in one-time programmable memory stores key startup configurations, drastically reducing external components typically used to set output voltage and sequence of external regulators. Regulator parameters are adjustable through high-speed I2C after startup, offering flexibility for different system states.
