Hi I have new design for powering up SC589 ICs

I find that the IC gets really hot when running And the 3.3v does not regulate properly.

If the DC Input volts is lower than 6v I cant get 3.3v  even with no load.

The Measured DC load on the 3.3v is 1 A and the Volts Drop to 3.1v

The PCB is a 12 Layer Board with Large Copper Pours so plenty of thermal dissipation.


Can I Parallel SW3 with SW4 by joining the pins together and using the single common inductor L8  and setting the Parralel option. Or is it necessary to have separate inductors .
