Pin Description
Pin Name
Pin Number
Description
EN
1
Chip Enable Pin. Drive EN above 1.5V to turn on the part. Drive EN below 0.3V to turn it off. Do not leave EN floating.
GND
2
Analog ground pin.
SW
3
Power Switch Output. It is the switch node connection to Inductor. This pin connects to the drains of the internal P-ch and N-ch MOSFET switches.
VIN
4
Power Supply Input. Must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor.
FB
5
Output Voltage Feedback Pin. An internal resistive divider divides the output voltage down for comparison to the internal reference voltage.
