As power is increased to about 42 watts (42V @ 1amp) LED output starts flashing. Noticed SS pin is dropping low quickly. From the data sheet page 13 I see 5 conditions that would cause a rapid discharge of the SS pin. They are CTRL 1 or 2 below 0.2V, UVLO low, Visp-Visn > 0.75V, and FB > 1.05V. I dont see any of these conditions being broken. The SS cap is being quickly discharge do switch to ground from Inhibit Control looks like its being activated. What could be going on?
