The LM5116 Webench® BuildIt PCB is designed to provide the design engineer with a way to check out their fully functional power converter based Webench Design based on the LM5116 controller IC. The PCB supports the buck topology and allows for wide input voltage ranges from 6V to 100V. The printed circuit board consists of 4 layers, 2 ounce copper top and bottom, 1 ounce copper internal layers on FR4 material with a thickness of 0.062 inches.

The complete details for using this PCB are part of your custom LM5116 buck Webench design, and are located on the BuildIt tab of the Webench Workspace of that design. To access your stored designs start with the Webench MyDesigns link. Once you locate and open your design, click on the BuildIt icon (looks like a shopping cart) and look in the Documentation column table for the Assembly Documentation link.
