4 Phase, 150 A Reference Design for Intel Arria 10 GX FPGAs using TPS53647

1 января 2018

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.
