PF8121 12-channel power management integrated circuit for high performance applications Rev. 6 — 18 October 2024Product data sheet 1 Overview The PF8121 is a power management integrated circuit (PMIC) designed for high performance consumer applications. It features seven high efficiency buck converters and four linear regulators for powering the processor, memory and miscellaneous peripherals. Built-in one-time programmable (OTP) 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 I 2 C after startup, offering flexibility for different system states.
