IN
(Pin 1):
Signal Input Supply. Decouple this pin to
SGND with a capacitor. SV
IN
must be greater or equal to
PV
IN
, however, the difference between SV
IN
and PV
IN
must
be less than 0.5V.
PGOOD (Pin 2):
Power Good Output. Open-drain logic
output that is pulled to ground when the output voltage is
not within
±
10% of regulation point.
I
TH
(Pin 3):
Error Amplifier Compensation Point. The
current comparator threshold increases with this control
voltage. Nominal voltage range for this pin is from 0.2V to
1.4V with 0.6V corresponding to the zero-sense voltage
(zero current).
V
FB
(Pin 4):
Feedback Pin. Receives the feedback voltage
from the output.
R
T
(Pin 5):
Oscillator Resistor Input. Connecting a resistor
to ground from this pin sets the switching frequency.
V
REF
(Pin 6):
Reference Voltage Input. The positive input
of the internal error amplifier senses one-half of the
voltage at this pin through a resistor divider.
RUN/SS (Pin 7):
Run Control and Soft-Start Input. Forcing
this pin below 0.5V shuts down the LTC3413. In shutdown
all functions are disabled drawing < 1
μ
A of supply current.
A capacitor to ground from this pin sets the ramp time to
full output current.
SGND (Pin 8):
Signal Ground. All small-signal compo-
nents and compensation components should connect to
this ground, which in turn connects to PGND at one point.
PV
IN
(Pins 9, 16):
Power Input Supply. Decouple this pin
to PGND with a capacitor.
SW (Pins 10, 11, 14, 15):
Switch Node Connection to
Inductor. This pin connects to the drains of the internal
main and synchronous power MOSFET switches.
PGND (Pins 12, 13):
Power Ground. Connect this pin
closely to the (–) terminal of C
IN
and C
OUT
.
EXPOSED PAD (Pin 17):
Should be connected to SGND.
