SW (Pin 1): 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.
GND (Pin 2): Signal and Power Ground. Provide a short
direct PCB path between GND and the (–) side of the input
and output capacitors.
VOUT (Pin 3): Output voltage sense and drain of the internal
synchronous rectier. PCB trace from VOUT to the output
lter capacitor (4.7F minimum) should be as short and
wide as possible.
SHDN (Pin 4): Logic Controlled Shutdown Input. There
is an internal 4MΩ pull-down on this pin.
SHDN = High: Normal operation
SHDN = Low: Shutdown, quiescent current < 1A
FB (Pin 5): Feedback Input to the gm Error Amplier. Con-
nect resistor divider tap to this pin. The top of the divider
connects to the output capacitor, the bottom of the divider
connects to GND. Referring to the Block Diagram, the output
voltage can be adjusted from 1.6V to 5.25V by:

.
VIN (Pin 6): Input Supply Pin. Connect a minimum of 1F
ceramic decoupling capacitor from this pin to ground using
short direct PCB traces.
Exposed Pad (Pin 7): The Exposed Pad must be soldered
to the PCB ground plane. It serves as an additional ground
connection and as a means of conducting heat away from
the package.
