APPLICATION INFORMATION (continued)
In many applications, the output voltage of the converter is intentionally allowed to droop as load current
increases. This approach (sometimes referred to as active load line programming) allows for better use of the
regulation window and reduces the amount of the output capacitors required to handle the same load current
step. A resistor from the REF pin to the DROOP pin sets the desired value of the output voltage droop.
where:
VDROOP is the value of droop at maximum load current IOUT
NPH is number of phases
RCS is the current-sense resistor value
2500
is the inversed value of transconductance from the current sense pins to DROOP
VCSx, are the average voltages on the current sense pins
