is used to implement the Droop Function. This current IFB (equal to the sum of both IINFOx) 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:
Since IFB depends on the current information about the two phases, the output characteristic vs. load cur-
rent is given by:
Where ILOAD is the output current of the system and RDROOP is its equivalent output resistance.
The feedback current is equal to 50
A at nominal full load (IFB = IINFO1 + IINFO2) and 70A at the OC in-
tervention threshold, so the maximum output voltage deviation is equal to:

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
