Pin Function
No Connect.
Power Ground.
Ground.
Feedback. This pin is the feedback to the PWM to control the output current. Attach to
a current sense resistor.
VCC. Battery input to run the IC.
Switch Node. Connection to internal power MOSFET. Attach to inductor and diode.
Enable. A logic low turns on the converter. A logic high or open turns off the converter.
A PWM signal on this pin dims the output.
