Pin Description

Name

Description

SW

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

EMI.

GND

GND pin

SET

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

CTRL

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.

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

NC

No connection
