Configurable multi-rail PMIC for Xilinx MPSoCs and FPGAs

The

TPS650864 device family is a single-chip power-management IC (PMIC) designed for

Xilinx Zynq multiprocessor

system-on-chip (MPSoCs) and field programmable gate array (FPGA) families. The

TPS650864 offers an input range of 5.6V to 21V, enabling a wide range of

applications (see the Device Comparison Table). The device is targeted for

wall-powered applications or 2S, 3S, or 4S Li-Ion battery packs (NVDC or non-NVDC

power architectures). See the Typical Application section for 5V input supplies. The D-CAP2

and DCS-Control high-frequency voltage regulators use small passives 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 that have

fast load switching. An I2C interface allows simple control either by an

embedded controller (EC) or by an SoC. The PMIC comes in an 8mm × 8mm, single-row

VQFN package with thermal pad for good thermal dissipation.
