4 Phase: 150 A Reference Design for Intel Arria 10 GX FPGAs using TPS53647
Description
A 4 phase buck regulator design fully complaint to power the core rail of Intel Arria 10 GX FPGAs: specifically the 10AX115U145IVG variant. Integrated PMBus allows for easy output voltage setting and telemetry of key design parameters. The design enables programming: configuration: Smart VID adjustment: and control of the power supply: while providing monitoring of input/output voltage: current: power: and temperature. It uses TI's Fusion Digital Power Designer for programming: monitoring: validation and characterization of the FPGA power design.
