Description
Switching Pin. This is the collector of the internal NPN power switch. Connect to
inductor and diode. Minimize the metal trace area connected to this pin to reduce
EMI.
Ground Pin. Connect directly to local ground plane.
Feedback Pin. Reference voltage is 200mV. Connect LEDs and a resistor at this
pin. LED current is determined by the resistance and CTRL voltage.
Shutdown Pin and Dimming Control Pin.
VCTRL > 1.8V generates full-scale LED current
VCTRL < 0.4V chip is off
Switching from 04V to 2.0V, PWM duty cycle controls the LED current
Input Supply Pin. Bypass this pin with a capacitor as close to the device as possible
