8.2.2.1 Custom Design with WEBENCH Tools

Click here to create a custom design using the TPS61175 device with the WEBENCH® Power Designer.

  1. Start by entering your VIN, VOUT and IOUT requirements.
  2. Optimize your design for key parameters like efficiency, footprint and cost using the optimizer dial and compare this design with other possible solutions from Texas Instruments.
  3. WEBENCH Power Designer provides you with a customized schematic along with a list of materials with real time pricing and component availability.
  4. In most cases, you will also be able to:
    • Run electrical simulations to see important waveforms and circuit performance,
    • Run thermal simulations to understand the thermal performance of your board,
    • Export your customized schematic and layout into popular CAD formats,
    • Print PDF reports for the design, and share your design with colleagues.
