is used to implement the Droop Function. This current I
FB
(equal to the sum of both I
I
NFOx
) is sourced from
the FB pin. Connecting a resistor between this pin and Vout, the total current information flows only in this
resistor because the compensation network between FB and COMP has always a capacitor in series (See
fig. 7). The voltage regulated is then equal to:
V
OUT
VID* R
FB
I
FB

Since I
FB
depends on the current information about the two phases, the output characteristic vs. load cur-
rent is given by:
V
OUT
VID* R

I
LOAD

Where I
LOAD
is the output current of the system and R
DROOP
is its equivalent output resistance.
The feedback current is equal to 50
μ
A at nominal full load (I
FB
= I
INFO1
+ I
INFO2
) and 70
μ
A at the OC in-
tervention threshold, so the maximum output voltage deviation is equal to:

Figure 7. Active Droop Function Circuit
REMOTE VOLTAGE SENSE
A remote sense buffer is integrated into the device to allow output voltage remote sense implementation
without any additional external components. In this way, the output voltage programmed is regulated be-
tween the remote buffer inputs compensating motherboard trace losses or connector losses if the device
