Ground. Connect GND to system ground and the input bypass capacitor as
close to the IC as possible. Connect GND to the exposed pad directly under
the IC.
Transfer Capacitor 1 Negative Connection. Connect a 1µF ceramic capacitor
from C1P to C1N.
Supply Voltage Input. Connect a 1µF ceramic capacitor from IN to GND. The
input voltage range is 2.7V to 5.5V.
Transfer Capacitor 2 Negative Connection. Connect a 1µF ceramic capacitor
from C2P to C2N.
