Altera Cyclone III FPGA Power Reference Design with TPS65023


Design files


This TPS65023-based reference design is a compact, integrated power solution for Altera® Cyclone® III SoC (out of the Cyclone® series family of products). This design showcases TPS65023 as an all-in-one IC used to supply the rails needed for powering the Cyclone® III SoC.  The TPS65023 offers simple, flexibile output voltages and sequencing. The voltages on the DC/DC Converters can be set through software or via external resistor divider. This power management IC has a input range from 2.5 – 6V and can be run from a single 5V supply or from a single cell Li-Ion battery. This design has been tested and verified for industrial applications (-40°C to 105°C)

  • Offers 3 highly efficient, externally adjustable DC-DC converters with integrated FETs and 2 externally adjustable general purpose LDO to power the Cyclone III
  • Separate enables for each converter
  • Built-in Current Limit on all rails
  • Qualified for Industrial Applications (-40ºC to 105ºC)
  • This design includes a test report, an EVM Guide, and design files to help accelerate the evaluation process
