Droop Configuration
The terminology for droop is the same as load line or voltage positioning as defined in the Intel CPU VCORE
specification. Based on the actual tolerance requirement of the application, load-line set points can be defined to
maximize either cost savings (by reducing output capacitors) or power reduction benefits.
Accurate droop voltage response is provided by the finite gain of the droop amplifier. The equation for droop
voltage is shown in Equation 2.
where
low-side on-resistence is used as the current sensing element
ACSINT is a constant, which nominally is 53 mV/A.
I(L) is the DC current of the inductor, or the load current
RDROOP is the value of resistor from the COMP pin to the VREF pin
GM is the transconductance of the droop amplifier with nominal value of 1 mS
(2)
(3)
Therefore, if a 5-m
Ω load line to the system agent rail is desired, the calculated RDROOP is approximately 10 kΩ.
