Description

The K2E requires the use of AVS SmartReflex control for the CVDD core voltage. This design provides method of generating the proper voltage using software and the PMBus interface of the TPS544C25. The circuit can be implemented on the XEVMK2EX.

Features
  • Provides the AVS SmartReflex Core voltage required by the K2E
  • Meets the 5% voltage requirement for CVDD
  • Uses the PMBus interface on the TPS544C25 for control
  • Uses software to send the VOUT command
  • Complete system reference with schematics, BOM, design files, and HW Design Guide, implemented on the K2E EVM platform for testing and evaluation
