Name

Description

P1

AGND

Analog Ground. P1 must be soldered to the PCB ground.

Supply Voltage Input.

2PGND

Power Ground. This pin is connected to the internal MOSFET switches. This pin must

be externally connected to AGND.

3EN

Enable Input. Logic high enables the chip and logic low disables the chip, reducing

the supply current to less than 1µA. Do not float this pin.

4

FB

Feedback Input. Adjustable voltage option, connect this pin to the resistor divider.

5NC

No Connection Pin.

6SW

Switching Node. This pin is connected to the internal MOSFET switches.
