Pin Name Pin
Number Pin Description
EN 1 Enable control. Pull high to turn on. Do not float.
GND 2 Ground pin
LX 3 Inductor pin. Connect this pin to the switching node of inductor
IN 4 Input pin. Decouple this pin to GND pin with at least 1uF ceramic cap
FB 5 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).Add optional C
1
(10p-47pF) to speed up transient
response.
