Design files

Overview

This reference design is a 3.3Vin to 0.9V @ 10A power supply in a small form-factor, cost-effective design. It uses the TPS40400 controller in conjunction with the CSD87381P (a high and low side FET IC). The TPS40400 features full PMBUS telemetry for enhanced monitoring and control. The PMP20084 board is a 4-layer, 2-oz copper weight per layer board.

Features
  • 3.3v input to 0.9V/10A output
  • 2inch x 2inch. 2oz, 4-layer. 0.835 in2 on a two sided PCB
  • 400KHz PMBus switching regulators for 10A low voltage rail
  • Supported by TI’s Fusion GUI Digital Power Designer
  • 100% green PMBus power solution for 0.9V/10A ASIC/FPGA core rail
