PI FU
CAP:
Charge Compensation Pin. A capacitor to V
CC
pro-
vides charge required by the PGate level shift capacitor
during supply transitions. The charge compensation ca-
pacitor must be larger than the gate drive capacitor.
C
T
:
External Capacitor. From this pin to ground sets the
operating frequency. (The frequency is also dependent
upon the ratio V
OUT
/V
IN
).
I
TH
:
Gain Amplifier Decoupling Point. The regulator cur-
rent comparator threshold increases with the I
TH
pin
voltage.
SENSE
:
Connects to internal resistive divider which sets
the output voltage. The Sense
pin is also the (–) input of
the current comparator.
U
SENSE
+
:
The (+) Input for the Current Comparator. A
built-in offset between the Sense
+
and Sense
pins, in
conjunction with R
SENSE
, sets the current trip threshold.
V
FB1, 2
:
These pins receive the feedback voltage from an
external resistive divider used to set the output voltage of
the adjustable section.
MSHDN:
Master Shutdown Pin. Taking MSHDN high
shuts down V
CC
and all control circuitry.
SHDN1, 3, 5:
These pins shut down the individual regula-
tor control circuitry (V
CC
is not affected). Taking SHDN1,
3, 5 pins high turns off the control circuitry of adjustable
1, 3.3V, 5V sections and holds both MOSFETs off. Must be
at ground potential for normal operation.
