Pin Functions
PGND:Connect all power ground components to a PGND
plane which should also connect directly to this pin. Use a
trace or via to connect the AGND plane to the PGND plane.
Please see Layout Considerations under the Operation sec-
tion for more details on layout suggestions.
SW: This is the drain of the internal NMOS power switch.
Minimize the metal trace area connected to this pin to mini-
mize EMI.

nect between V
SWI: PMOS switch input. Source connection of PMOS de-
vice.
SWO: PMOS switch output. Drain connection of PMOS
device.

SWC: PMOS switch control pin. This pin creates an AND
function with the delay time after the output of the switching
regulator has reached 85% of its nominal value. To ensure
the PMOS switch is in the correct state, apply a voltage
above 1.5V to this pin to turn on the PMOS switch and apply
a voltage below 0.7V to turn off the PMOS switch.
AV
buffer. Bypass this pin with a capacitor as close to the device
as possible, about 100nF, if connected directly to the output
of the boost DC/DC switching regulator. The capacitor
should connect between AV
