Pin Functions

NO. NAME DESCRIPTION
1 AVIN Input Voltage for Control Circuitry
2 EN Enable
3 SGND Low noise ground
4 SS Soft-Start Pin
5 NC No Connect. This pin must be tied to ground.
6,7 PVIN Input Voltage for Power Circuitry
8,9 SW Switch Pin
10,11 PGND Power Ground
12,13 NC No-Connect. These pins must be tied to ground.
14 SNS Output Voltage Sense Pin
Exposed Pad EP The exposed pad is internally connected to GND, but it cannot be used as the primary GND connection. The exposed pad should be soldered to an external GND plane.
