Description

1EN

Active-High Enable Input. A logic low on this pin shuts down the device and

reduces the supply current to 0.1µA.

2VCC

+2.7V to +5.5V Supply Voltage. Bypass this pin to GND with a

≥1µF capacitor.

3SWVIN

Shutdown Disconnect Switch In

4POK

Power-OK.

5LX

Inductor. The drain of the internal N-channel MOSFET.

Note: This pin is high impedance in shutdown.

6SWOUT

Shutdown Disconnect Switch Out. Disconnects the input from the output during

shutdown.

7GND

Ground. This pin and pin 9 must be connected to GND to ensure normal operation.

8FB

9GND

Ground. This pin and pin 7 must be connected to GND to ensure normal operation.
