(Pins 1, 8):
The (–) Inputs to the
Differential Current Comparators.

/RUN1, I
TH
/RUN2 (Pins 2, 6):
These pins each serve
two functions. Each pin serves as the error amplifier
compensation point as well as the run control input for the
respective controller. Forcing one pin below 0.35V causes
the functions associated with that controller to be shut
down. Forcing both I
TH/RUN
pins below 0.35V causes the
device to be shut down. Nominal operating voltage range
on these pins is from 0.7V to 1.9V.
V
FB1
, V
FB2
(Pins 3, 5):
Each receives the remotely sensed
feedback voltage for each controller from an external
resistive divider across the output.
SGND (Pin 4):
Signal Ground.
PLLLPF (Pin 7):
Serves as the lowpass filter point for the
PLL and as the voltage control input to the internal
oscillator. Normally, a series RC is connected between this
pin and ground when synchronizing to an external clock.
Nominal voltage range is from 0V to 2.4V. Frequency can
be set by forcing this pin with a voltage. Tying this pin to
GND selects 300kHz. Tying to V
IN
or a voltage
≥
2.4V
selects 750kHz. Floating this pin selects 550kHz opera-
tion.
SENSE2
+
(PV
IN2
), SENSE1
+
(PV
IN1
) (Pins 9, 16):
The (+)
Inputs to the Differential Current Comparators. These pins
also power the gate drivers.
EXTCLK/MODE (Pin 10):
External Clock Input. Applying a
clock to this pin causes the internal oscillator to phase-
lock to the external clock (nominal lock frequency range
between 300kHz and 750kHz). This also disables Burst
Mode
operation but allows pulse-skipping at low load
currents.
Forcing this pin high enables Burst Mode operation.
Forcing this pin low enables pulse-skipping mode. In
these cases, the frequency of the internal oscillator is set
by the voltage on the PLLLPF pin. If the PLLLPF voltage is
not set externally, the frequency internally defaults to
550kHz.
PGOOD(Pin 11):
Power Good Output Voltage Monitor
Open-Drain Logic Output. This pin is pulled to ground
when the voltage on either feedback pin (V
FB1
, V
FB2
) is not
within
±
8% of its nominal set point. PGOOD is pulled low
when channel 1 or both channels are shut down. When
channel 2 is shut down and channel 1 enabled, the
PGOOD output indicates the state of V
FB1
only.
PGATE2, PGATE1 (Pins 12, 14):
Gate Drivers for the
External P-Channel MOSFETs. These pins swing from 0 to
SENSE
+
(PV
IN
).
PGND (Pin 13):
Ground Pin for Gate Drivers.
V
IN
(Pin 15):
Chip Signal Power Supply Input. This pin
powers the entire chip except for the gate drivers.
