9 Revision History

Changes from Revision D (February 2024) to Revision E (April 2024)

  • Adjusted install workflow for SDK release of softwareGo

Changes from Revision C (July 2022) to Revision D (February 2024)

  • Updated document to reflect new hardware revision of TIDA-010054. This includes new gate drivers, bias supplies, current sensors, and the C2000 MCU. The thermal design is improved and relays are added to the secondary side output. Software is updated to support new hardware features and extended-phase-shift control for improved light load efficiency is added. Two additional Labs for closed-loop voltage and current control are included for reverse power flow operation.Go
