Function
1
VP
Input power pin; connected to the source of the P-channel MOSFET.
Connect to the input capacitor.
2
VIN
Input bias voltage for the converter.
3
GND
Non-power signal ground pin.
4
FB
Feedback input pin. Connect this pin to an external resistive divider for
adjustable output.
5
N/C
No connect.
6
EN
Enable pin. A logic high enables normal operation. A logic low shuts down
the converter.
7
LX
Switching node. Connect the inductor to this pin. It is connected internally to
the drain of both high- and low-side MOSFETs.
8
PGND
Input power return pin; connected to the source of the N-channel MOSFET.
Connect to the output and input capacitor return.
EP
Exposed paddle (bottom): connect to ground directly beneath the package.
