The TI Power Designer[0] is a great resource. Obviously it will only show you TI parts, but it's very helpful to get a base design. You can filter by complexity (roughly BoM count), size, cost etc based on the parameters (input voltage range, output voltage range, power etc). The designs usually have a reference layout as well. 0: https://webench.ti.com/power-designer/ https://webench.ti.com/power-designer/
