TI TPS6508640RSKR

The TPS650864 device family is a single-chip power management IC (PMIC) designed specifically for the Xilinx Zynq multiprocessor system-on-chip (MPSoC) and FPGA series. The TPS650864 device supports an input voltage range of 5.6V to 21V, enabling a wide range of applications. The device is suitable for wall-powered applications or 2-, 3-, and 4-cell series-connected Li-ion battery packs (NVDC or non-NVDC power architectures). D-CAP2 and DCS-Control high-frequency regulators use compact passive components to minimize solution size. The D-CAP2 and DCS-Control topologies offer excellent transient response performance, making them ideal for processor core and system memory voltage rails with fast load switching. The I2C interface enables easy control via an embedded controller (EC) or SoC. The PMIC measures 8mm × 8mm in a single-row VQFN package with an exposed thermal pad for improved thermal dissipation.
