Offset (Optional)
The OFFSET pin allows programming a positive offset (V
connecting a resistor R
one already introduced during the production stage for the Intel VR10,VR11 Mode.
The OFFSET pin is internally fixed at 1.240V
connecting the resistor R
then properly sunk from the FB pin as shown in
programmed as follow:
Offset resistor can be designed by considering the following relationship (R
Droop effect):
Offset automatically given by the DAC selection differs from the offset implemented through
the OFFSET pin: the built-in feature is trimmed in production and assures ±0.5% error
(±0.6% for the AMD DAC) over load and line variations.
