Output 11.35 V / 2 A
IC revisionA

Description

The PMP10555 reference design provides all the power supply rails necessary to power Xilinx® Ultrascale® 16nm family of FPGAs/SoCs in a mobile radio basestation application. This design uses a PMBus compatible 20A integrated FET buck converter for the core and two multi-output buck regulator ICs to provide the remaining supplies necessary rails to power the FPGA. It also features two LM3880's for flexible power up and power down sequencing. This design uses a 12V input.

Features

  • Provides all the power supply rails needed for a Xilinx® Ultrascale® Series FPGA for a mobile radio basestation
  • Design optimized to support a 12V input
  • PMBUS interface with output voltage and current reporting for the core voltage
  • On board power up and power down sequencing
  • Voltage margining at the core voltage
