slope, Rdroop is 0.0021 (V/A), we can then calculate for Roc
as shown in Equation 17.
Note, if the droop load line slope is not -0.0021 (V/A) in the
application, the overcurrent setpoint will differ from
predicted.
A capacitor may be added in parallel with Roc to improve
noise rejection but the Roc*capacitor time constant cannot
exceed 20µs. Do not remove Roc if overcurrent protection is
not desired. The maximum Roc is 30K.
