Table 1. Pin Descriptions - 5-Pin SOT-23
Pin Name Function
1 SW Output switch. Connect to the inductor, output diode.
2 GND Signal and power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin.
3 FB Feedback pin. Connect FB to external resistor divider to set output voltage.
Dimming and shutdown control input. Logic high enables operation. Duty Cycle from 0 to 100%. Do not allow this pin
4 DIM
to float or be greater than VIN + 0.3V.
5 VIN Supply voltage pin for power stage, and input supply voltage.
Table 2. Pin Descriptions - 6-Pin WSON
Pin Name Function
