See Note 2.
Note 2: VRM 9 VID Codes are achieved by
terminating pin 9 to ground with an equivalent
resistance of 4.77K.
Note 3: Output voltage Vs. VID can be modified by
minus 400mV at each VID by applying a reference
to pin 9. Applied reference should have a Thevenin
Equivalent Voltage of 400mV and Thevenin
Equivalent Resistance of 4.77K. Application of this
offset reference must be synchronized with enabling
the VRM. See Application Circuit 1.
Note 4: If pin 9 is floating the resulting output
Voltage will be 50% of the values in the VID table at
each VID setting.
