Pin Descriptions

Pin

Number

Pin

Name

Function

1

PGND

Main power ground return pin. Connect to the output and input capacitor return.

2

PVIN

Input power supply tied to the source of the high side P-channel MOSFET.

3

VIN

Power supply; supplies power for the internal circuitry.

4

FB

Feedback input pin. Feedback voltage to internal error amplifier, the threshold voltage is 0.6V.

5

AGND

Analog ground. This pin is internally connected to the analog ground of the control circuitry.

6

EN

Enable pin. A logic low disables the converter and it consumes less than 1μA of current.When connected high, it

resumes normal operation.

7, 8

SW

Switching node. Connect the inductor to this pin. It is internally connected to the drain of both high and low side

MOSFETs.
