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 100mV. 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 0.4V 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
