I’m having difficulty setting up an 8-rail fusion digital power system using 2 x UCD9246. I can’t get UCD9246 #1; Rail #2 or UCD9246C #2; Rail #2 to power up reliably. I believe the hardware is ok as all the other rails work.
Also I get the following warning when swapping between rails in Design mode when swapping between Rails #2, #3 & #4 on either UCD9246C
UCD9246 #1
Rail #1: PTD08A020W 1V0 @ 20A
Rail #2: UCD74106 3V3 @ 6A
Rail #3: UCD74106 1V5 @ 6A
Rail #4: UCD74106 2V5 @ 6A
UCD9246C #2
Rail #1 = PTD08A020W 1V0 @ 20A
Rail #2: UCD74106 2V5 @ 6A
Rail #3: UCD74106 1V2 @ 6A
Rail #4: UCD74106 1V8 @ 6A
Attached is the PSU circuit pages & the Fusion program files.
