Pin Description

Enable control. Pull high to turn on. Do not float.

Ground pin. The paddle must be soldered to the ground plane on the PCB.

Inductor pin. Connect this pin to the switching node of inductor.

Input pin. Decouple this pin to GND paddle with at least 10uF ceramic cap.

Output Feedback Pin. Connect this pin to the center point of the output

resistor divider (as shown in Figure 1) to program the output voltage:

Vout=0.6*(1+R1/R2).
