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 .
OK Found the Issue
The Bootstrap capacitor was damaged.
All fixed and running cool
