Pin Description/Functions
SW(Pin 1): Switch Pin. This is the drain of the internal
NMOS power switch. Minimize the metal trace area con-
nected to this pin to minimize EMI.
GND(Pin 2): Ground Pin. Tie directly to ground plane.
FB(Pin 3): Feedback Pin. Set the output voltage by selecting
values for R1 and R2 using:
LM2704MFX-ADJ

Connect the ground of the feedback network to an AGND
plane which should be tied directly to the GND pin.
SHDN(Pin 4): Shutdown Pin. The shutdown pin is an active
low control. Tie this pin above 1.1V to enable the device. Tie
this pin below 0.3V to turn off the device.
