Description
1
SW
Power Switch Input.
This is the drain of the internal NMOS power switch.
Minimize the metal trace area connected to this pin to minimize EMI.
2
GND
Ground. Tie directly to ground plan.
3
FB
Output voltage feedback input.
Set the output voltage by selecting values for R1 and R2 using:
Connect the ground of the feedback network to a GND plane.
4
EN
Enable, active high.
The enable pin is an active high control. Tie this pin above 2V to enable the device.
Tie this pin below 0.4V to turn off the device.
5
IN
Analog and Power input. Input Supply Pin.
Place bypass capacitor as close to Vin as possible.
