Decided I needed another bench supply for home and whipped this design up using their examples as a reference, looking for comments. With the right transformer it's easily capable of 1.2V - 36V @ 5A, it also has the option of adding a variable current limit simply by replacing a single resistor with a single pot. Very minimal component count.
National will sample the IC to you for free - you pay the postage if you're not a registered business with a business e-mail address or it's totally free if you do.
I've included the schematic and a bill of materials which is somewhat flexible.
