Description

Switch Pin. Connect inductor/freewheeling diode here. Minimize trace area at this pin to reduce

EMI.

GND pin

Set Nominal Output Current Pin. Configure the output current of the device.

Dimming and On/Off Control Input. Input voltage of 0.2V or lower forces the device into low

current standby mode and shut off the output. A PWM signal allows the output current to be

adjusted above or below the level set by the resistor connected to SET input pin.

The input impedance is about 50k, and if the pin is left open VCTRL = VREF

Input Supply Pin. Must be locally bypassed with a capacitor.

No connection
