Pin Name

1

SW

Switch (Output): Internal power MOSFET output switches.

2

EN

Enable (Input). Logic low will shut down the device, reducing the quiescent

current to less than 4µA.

3

VSC

Voltage scaling pin (input): A low on this pin will scale the output voltage

down to specified level.

4

SNS

5

CFF

Feed Forward Capacitor. Connect a 560pF capacitor.

6

AGND

Analog Ground.

7

VIN

Supply Voltage (Input): Requires bypass capacitor to GND.

8

PGND

Power Ground.
