Description

1

EN

Enable Input for the Regulator. A logic low on this pin disables the regulator.

2

NC

No Connect. Connect this pin to ground.

3

MODE

Operating Mode Pin. Connect this pin to ground; the regulator operates in hysteresis mode.

4

VID

Voltage Configuration Pin. Connect one resistor from this pin to ground to configure the output voltage of the

regulator.

5

FB

Feedback Sensing Input for the Regulator.

6

VINOK

Input Power-Good Signal. This open-drain output is the power-good signal for the input voltage.

7

AGND

Analog Ground.

8

PGND

Power Ground.

9

SW

Switching Node Output for the Regulator.

10

PVIN

Power Input for the Regulator.

EPAD

Exposed Pad. Solder the exposed pad to a large external copper ground plane underneath the IC for thermal

dissipation.
