MC32PF8121G5EP数据手册恩XP中文资料规格书

描述 Description

The PF8121 is a power management integrated circuit (PMIC) designed for high-performance consumer applications. This PMIC IC features seven high-efficiency buck converters and four 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.
