Efficiency is of high concern for my current design, hence the choice of a resonant LLC. Despite the datasheets not providing any evidence a low input voltage (say, 20V+) isn't valid, I see a lot of chatter that says this isn't the proper topology, and the WebBench tools don't allow for sim at that low of a voltage. Can someone elucidate the reasoning behind that limitation?
My design: Input = 27-36V (28V nominal), Output = 12V @ 25A
