3414fb
PGND (Pins 1, 10, 11, 20): Power Ground. Connect this
pin closely to the (–) terminal of CIN and COUT.
RT (Pin 2): Oscillator Resistor Input. Connecting a resistor
to ground from this pin sets the switching frequency.
SYNC/MODE (Pin 3): Mode Select and External Clock
Synchronization Input. To select Forced Continuous, tie to
SVIN. Connecting this pin to a voltage between 0V and 1V
selects Burst Mode operation with the burst clamp set to
the pin voltage.
RUN/SS (Pin 4): Run Control and Soft-Start Input. Forcing
this pin below 0.5V shuts down the LTC3414. In shutdown
all functions are disabled. Less than 1
μA of supply current
is consumed. A capacitor to ground from this pin sets the
ramp time to full output current.
SGND (Pin 5):Signal Ground. All small signal components
and compensation components should connect to this
ground, which in turn connects to PGND at one point.
NC (Pin 6): Open. No internal connection.
PVIN (Pins 7, 14): Power Input Supply. Decouple this pin
to PGND with a capacitor.
SW (Pins 8, 9, 12, 13): Switch Node Connection to
Inductor. This pin connects to the drains of the internal
main and synchronous power MOSFET switches.
NC (Pin 15): Open. No internal connection.
SVIN (Pin 16): Signal Input Supply. Decouple this pin to
SGND with a capacitor.
PGOOD (Pin 17): Power Good Output. Open drain logic
output that is pulled to ground when the output voltage is
not within
±7.5% of regulation point.
ITH (Pin 18): 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 0.4V corresponding to the zero-sense voltage
(zero current).
VFB (Pin 19): Feedback Pin. Receives the feedback voltage
from a resistive divider connected across the output.
Exposed Pad (Pin 21): Should be connected to SGND and
soldered to the PCB.
