SW
Switch node (Input): Internal power BIPOLAR collector.
2
GND
Ground (Return): Ground.
3

Supply (Input): 2.5V to 10V for internal circuitry.
1
OVP
Overvoltage protection (Input): Connect to the output.
4
AGND
Analog ground.
8
PGND
Power ground.
5
NC
No connect (no internal connection to die).
EP
GND
Ground (Return): Exposed backside pad.
