SwitcherPro™ Online or Desktop Design software allows you to design power supplies with Texas Instruments TPS40K™ controllers, low-power DC/DC converters and SWIFT™ (TPS54xxx) point-of-load step-down DC/DC products. Use SwitcherPro power supply design software to create, manage and share custom power supply designs. This software provides EVM designs that you can use for reference or starting points for custom power supply designs. In addition, passive components such as inductors and NexFet Transistors are now included in both the online and desktop applications. The desktop application allows more flexibility in creating power supply designs since there is no need to be connected to the internet. Design and go at your own pace.

NOTE: New devices are no longer being added to the tool. . Please go to WEBENCH® Power Designer for your power supply needs. Many devices from SwitcherPro have already been added to WEBENCH Power Designer, and we have added more capabilities like simulation, PCB/schematic/simulation export, and WebTHERM™ thermal simulation. You can find all of TI’s power products available in Power Designer here. Power Designer allows you to optimize, design, change components and edit the schematic, simulate, run WebTHERM thermal simulation and export your PCB design.


Whether using the online or desktop application, SwitcherPro power supply design software provides a unique combination of features.
