LTspice and XFAB - The Unbeatable Combination

A work of art - a 4 MHz switcher with SKIP mode implemented. Everything's macromodeled at this point except the switches and some of the logic cells.. Showing a sweep of the load with VIN 3.3V, Vo 5.625V (nom, this is the load-line architecture).

Now, time to try prototyping a hysteretic boost using what I just learned today..
