Texas Instruments TPS650860 Configurable Multi-Rail PMIC
Texas Instruments TPS650860 Configurable Multi-Rail PMIC is a single-chip power management IC designed for multicore processors, FPGAs, and other System-on-Chips (SoCs). The Texas Instruments TPS650860 offers an input range of 5.6V to 21V, enabling a wide range of applications. The device is well suited for NVDC and non-NVDC power architecture using 2S, 3S, or 4S Li-Ion battery packs. 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, 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.
