FB and COMP has always a capacitor in series (See fig. 8). The voltage regulated by each device is then equal
to:
Where I
OUT
is the output current of each device (equal to the total load current I
LOAD
divided by the number of
devices N)
Since I
FB
depends on the current information about the two phases of each device, the output characteristic vs.
load current is given by:
Where R
OUT
is the equivalent output resistance due to the droop function and I
OUT
is still the output current of
each device (that is the total current delivered to the load I
LOAD
divided by 2.
Figure 7. Output transient response without (a) and with (b) the droop function

The feedback current is equal to 50

A at nominal full load (I

) and 70

A at the OCP interven-
tion threshold, so the maximum output voltage deviation is equal to:
