Function
No Connect
Power ground pin. Place PGND and output capacitor GND close together.
Supply voltage for power stage, and input supply voltage.
Dimming & shutdown control input. Logic high enables operation. Duty Cycle from 0 to 100%. Do not allow
this pin to float or be greater than VIN + 0.3V.
Feedback pin. Connect FB to external resistor divider to set output voltage.
Signal ground pin. Place the bottom resistor of the feedback network as close as possible to this pin & pin 5
Output switch. Connect to the inductor, output diode.
No Connect
Signal & Power ground. Connect to pin 2 & pin 6 on top layer. Place 4-6 vias from DAP to bottom layer GND
plane.
