8.2.1.2.1 Custom Design With WEBENCH® Tools

Click here to create a custom design using the TPSM63603 device with the WEBENCH® Power Designer.

  1. Start by entering the input voltage (VIN), output voltage (VOUT), and output current (IOUT) requirements.
  2. Optimize the design for key parameters such as efficiency, footprint, and cost using the optimizer dial.
  3. Compare the generated design with other possible solutions from Texas Instruments.

The WEBENCH Power Designer provides a customized schematic along with a list of materials with real-time pricing and component availability.

In most cases, these actions are available:

  • Run electrical simulations to see important waveforms and circuit performance.
  • Run thermal simulations to understand board thermal performance.
  • Export customized schematic and layout into popular CAD formats.
  • Print PDF reports for the design, and share the design with colleagues.
