More generally, the TLVM13640 module is designed to operate with a wide range of external components
and system parameters. However, the integrated loop compensation is optimized for a certain range of output
capacitance.
9.2.1.2 Detailed Design Procedure
9.2.1.2.1 Custom Design With WEBENCH® Tools
Click here to create a custom design using the TLVM13640 module with 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.
