LM2577 High Current with mosfet

[tomshirvo]

So I am just wondering if with this LM2577 if I can use the "Switch" pin to connect to a mosfet or transistor to allow more than 3A of output current capacity. I know I would also require the other passive components to be rated for the current but I am looking at a 10A output. I want to be able to get 6V to 12V with 10A output!

Is this possible?

Not without a much larger pile of logic.  Those things are ancient, slow and inefficient, anyways -- there are better around!

Go with a modern controller, e.g.

for buck, which is also synchronous (better efficiency at low output voltages, if you need it), or
http://www.ti.com/product/lm3478
for boost (which is peak current mode, so also mind your inductor selection).
