2.5 ? R DROOP
V OC . Once the droop voltage is greater than V OC , the PWM
drives will turn off and PGOOD will go low.
The selection of R OC is given in Equation 37. Assuming an
overcurrent trip level, I OC , of 55A, and knowing from the Intel
specification of the load line slope, R droop = 0.0021 (V/A),
R OC is calculated by Equation 37.
I OC ? R droop 55 ? 0.0021
(EQ. 37)
– 6
Note, if the droop load line slope is not -0.0021 (V/A) in the
application, the overcurrent setpoint will differ from
predicted. In addition, due to the saturation limitations of the
DROOP amplifier, there is a maximum way-overcurrent
(WOC) set point for each VID code. The maximum OC set
point that will ensure WOC can be reached is expressed in
Equation 38:
1.75 – VID
(EQ. 38)
The WOC limitation is only problematic at very high VID
settings (~1.350V and above).
