Current Feedback Selection and Filtering
Differential Voltage Feedback and termination
A phase can be disabled by pulling the corresponding xCSPx pin to 3.3V.
Default setting for CPU: 3 phase operation
Dafault setting for GPU: 2 phase operation
CPU:
Phase disable can be done in revers
e order.Phase 3, then 2, then 1.
1. CPU 3 Phase operation: R47, R55, R69 open
2. CPU 2 Phase operation: R69 used 0ohm
3. CPU 1 Phase operation: R47, R55 used 0ohm
GPU:
1. GPU 2 Phase operation: R83, R89 open
2. GPU 1 Phase operation: R89 used 0ohm
