PIN FUNCTIONS
Load Step Response (Fixed
Frequency, 1.2V to 3.3V)
Load Step Response (Burst Mode
Operation, 1.2V to 3.3V, LTC3528)
SHDN (Pin 1): Logic Controlled Shutdown Input. There is
an internal 4M
Ω pull-down resistor on this pin.
SHDN = High: Normal operation
SHDN = Low: Shutdown, quiescent current < 1μA
FB (Pin 2): Feedback Input. Connect resistor divider tap
to this pin. The output voltage can be adjusted from 1.6V
to 5.25V by:
VV

OUT =+

.
PGOOD (Pin 3): Power Good Comparator Output. This
open-drain output is low when VFB < 10% from its regu-
lation voltage.
VOUT (Pin 4): Output Voltage Sense and Drain Connection
of the Internal Synchronous Rectier. PCB trace length
from VOUT to the output lter capacitor (4.7μF minimum)
should be as short and wide as possible.
SW (Pin 5): Switch Pin. Connect inductor between SW
and VIN. Keep PCB trace lengths as short and wide as
possible to reduce EMI. If the inductor current falls to
zero, or
SHDN is low, an internal anti-ringing switch is
connected from SW to VIN to minimize EMI.
PGND (Pin 6): Power Ground. Provide a short direct PCB
path between PGND and the (–) side of the input and
output capacitors.
SGND (Pin 7): Signal Ground. Provide a short direct PCB
path between SGND and the (–) side of the input and
output capacitors.
