Connection Diagrams
Figure 1. 6-Pin WSON Figure 2. 8-Pin eMSOP-PowerPAD
PIN DESCRIPTIONS 8-PIN eMSOP-PowerPAD
Pin Name Function
1 VIND Power Input supply.
2 VINA Control circuitry supply voltage. Connect VINA to VIND on PC board.
3, 5, 7 GND Signal and power ground pin. Place the bottom resistor of the feedback network as close as
possible to this pin.
4 EN Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than
VIN + 0.3V.
6 FB Feedback pin. Connect to external resistor divider to set output voltage.
8 SW Output switch. Connect to the inductor and catch diode.
DAP Die Attach Pad Connect to system ground for low thermal impedance, but it cannot be used as a primary GND
connection.
