ASrock B650 LiveMixer PCB Breakdown notes
🕑 Added 2023-02-06 13:04:34 +0000 UTCVcore
Renesas RAA229620 7phase
14x Renesas ISL99360 60A SPS
bulk output filter: 12x Nichicon FP12K 560uF TH poly
bulk input filter: 4x Apaq 5K 270uF TH poly
220nH inductors
500KHz 1.2V SPS only
200A 17W (typical overkill for AM5 boards)
300A 28W
400A 41W
500A 57W
voltage regulation and LLC:
optimal LLC is level 3
even at level 3 there's measurable undershoot because the load line is still very shallow
the board defaults to level 1 LLC everytime you change Vcore which is annoying.
