I have this circuit built, one with all through hole components, and one with the large current path in through hole, and the small resistors and capacitors are surface mount components, with the same IC.
The one with all through hole components is working like a charm!!!
However, when I apply a load to the surface mount version, then the output voltage drops to 20V...
On the surface mount version, C1, C3, L1, M1, R1, U1, and D1, are the same pieces as the working version.
So my question is, what components are not bulky enough to handle the load?
