The LM5116 Webench BuildIt PCB (LM5116BUCKEVM-BLDT) 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.
The LM5116 is a synchronous buck controller intended for step-down regulator applications from a high voltage or widely varying input supply. The control method is based upon current mode control utilizing an emulated current ramp. Current mode control provides inherent line feed-forward, cycle by cycle current limiting and ease of loop compensation. The use of an emulated control ramp reduces noise sensitivity of the pulse-width modulation circuit, allowing reliable control of very small duty cycles necessary in high input voltage applications.
