APPENDIX
Table of AMD VID Settings for NCP5386B Controller
The Grayhill 76PSB08ST 8 position switch used for
setting the output voltage of the synchronous buck
converter. Figure 7 below shows the pin assignment of the
switch. VID0 – VID5 set the output voltage. DAC, and EN
is the enable pin of the controller (controller reset). EN must
always be in the up position (1) unless a reset is performed.
To set the output voltage to 1.2 V, for example: VID0 = 0
(down), VID1, VID2, VID3 = 1 (up), VID4 = 0 (down), and
VID5, DAC, EN = 1 (up).
