Texas Instruments TPS650864xx Configurable Multi-Rail PMIC
Texas Instruments TPS650864xx Configurable Multi-Rail PMIC is a single-chip power-management IC (PMIC) designed for Xilinx Zynq multi-processor system-on-chip (MPSoCs) and field-programmable gate array (FPGAs). The TPS650864xx offers an input range of 5.6V to 21V, enabling a wide range of applications. The device is targeted for wall-powered applications or 2S, 3S, or 4S Li-Ion battery packs (NVDC or non-NVDC power architectures). The D-CAP2 and DCS-Control high-frequency voltage regulators use small inductors and capacitors to achieve a small solution size. The D-CAP2 and DCS-Control topologies have excellent transient response performance. This feature is ideal for processor core and system memory rails with fast load switching. An I2C interface allows simple control either by an embedded controller (EC) or an SoC.Features
