PIU
SW (Pin 1):
Switch Pin. This is the collector of the internal
NPN power switch. Minimize the metal trace area con-
nected to this pin to minimize EMI.
GND (Pin 2):
Ground. Tie this pin directly to the local
ground plane.
NFB (Pin 3):
Feedback Pin. Set the output voltage by
selecting values for R1 and R2 (see Figure 1):
