P8800 Block Diagram
説明
The P8800 is a 5W power management IC (PMIC) designed for NVDIMM and general purpose applications. It features three switching regulator channels and one VTT channel that is capable of sourcing and sinking current. It is powered from the PVIN input rail and has slew rate control on the internal input switches to reduce inrush current. The device utilizes an I²C interface for programming the PMIC to meet the specific requirements of the application.
