(SSOP/QFN)
PGOOD (Pin 1/Pin 30):
Open-Drain Logic Output. PGOOD
is pulled to ground when the output voltage is not within
±
7.5% of the regulation point.
SS (Pin 2/Pin 31):
Soft-start reduces the input power
sources’ surge currents by gradually increasing the
controller’s current limit. A minimum value of 6.8nF is
recommended on this pin.
SENSE
+
(Pin 3/Pin 1):
The (+) Input to the Current Sense
and Reverse Current Detect Comparators. The I
TH
pin
voltage and built-in offsets between SENSE
–
and SENSE
+
pins, in conjunction with R
SENSE
, set the current trip
threshold.
SENSE
–
(Pin 4/Pin 2):
The (–) Input to the Current Sense
and Reverse Current Detect Comparators.
I
TH
(Pin 5/Pin 3):
Current Control Threshold and Error Am-
plifier Compensation Point. The current comparator thresh-
old increases with this control voltage. The voltage ranges
from 0V to 2.4V.
