Pin Description

1

IN

Analog and Power input. Input Supply Pin.

2

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.

3

GND

Ground. Tie directly to ground plane.

4

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.

5

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.

6

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.

7

GND

Ground. Tie directly to ground plane.

8

GND

Ground. Tie directly to ground plane.
