(V)
As the load current increases from zero, the output voltage will
droop from the VID table value by an amount proportional to the
load current to achieve the load line. The ISL6363 can sense the
inductor current through the intrinsic DC Resistance (DCR) of the
inductors as shown in Figure 16 or through resistors in series
with the inductors as shown in Figure 22. In both methods,
capacitor C
droop amplifier converts C
source with the gain set by resistor R
for load line implementation, current monitor and overcurrent
protection.
Figure 9 shows the load line implementation. The ISL6363 drives
a current source I
When using inductor DCR current sensing, a single NTC element
is used to compensate the positive temperature coefficient of the
copper winding, thus sustaining the load line accuracy with
reduced cost.
