Did you check diode mode to ground?

You can't set the injected amp; that is decided by the resistance to ground and voltage injected.
Just let amp limit to max...

Well after pumping the amps to max and using the thermal camera found the problem to be U2800!!! hidden by the shield after removing this I can clearly see 1 burnt component!!!!

Removed U2800, replaced L7690 back and now I have 3V3_S5!!
