Pin Descriptions
Pin(s)
Name
Application Information
Voltage at this pin drives the internal NMOS power switch. A bootstrap capacitor is
connected between the BOOST and SW pins.
Signal and Power ground pin. Place the LED current-setting resistor as close as possible
to this pin for accurate current regulation.
Feedback pin. Connect an external resistor from FB to GND to set the LED Current.
Enable control input. Logic high enables operation. Toggling this pin with a periodic logic
square wave of varying duty cycle at different frequencies controls the brightness of LEDs.
Do not allow this pin to float or be greater than V
IN
+ 0.3V.
Input supply voltage. Connect a bypass capacitor locally from this pin to GND.
