8.2.2 Detailed Design Procedure

The typical application shows the LMG3614 pairing seamlessly with the Texas Instruments UCC25660 LLC controller to create a high-power-density, high-efficiency, 200W, LLC converter. The 200W LLC converter application is adapted from the typical application found in the UCC25660 data sheet. The UCC25660 data sheet typical application design procedure is not repeated here. Refer to the UCC25660 data sheet for the details in designing the LLC primary power stage and in using the UCC25660 controller. This detailed design procedure focuses on the specifics of using the LMG3614 in the application.
