Function
Switch pin. This is the drain of the internal power
switch. For minimum EMI, minimize the trace
area connected to this pin.
Ground pin. Connect pin 2 to ground.
LED (cathode) connection pin.
RESET pin. A resistor connected from pin 4 to
ground sets the LED current. This pin is also
used to dim the LEDs.
Shutdown pin.
Input supply pin. This pin should be bypassed
with a capacitor to ground. A 4.7µF capacitor
mounted close to the pin is recommended.
