TPS54226 Step-Down DCAP2 Mode Converter Evaluation Module


Order now


The TPS54226EVM-539 is a fully assembled and tested circuit for evaluating the TPS54428 synchronous step-down converter. The TPS54226EVM-539 operates from a 4.5-V to 18-V input and provides a 1.05-V output up to 2 A. The main control loop of TPS54226 uses D-CAP2™ mode control, which provides a very fast transient response without the need for external components in phase compensation. This solution also provides flexibility with adjsutable soft start feature and ingrated power good function.

  • Fast load transient response
  • Integrated power good function
  • Low output ripple and allows ceramic output capacitor
  • Highly efficient integrated MOSFETs optimized for low duty cycle applications
  • Adjustable soft start
  • Pre-biased soft start
  • 650-kHz switching frequency operation
  • Eco-mode: highly efficient in light load conditions
