Description
Switch Pin. Connect inductor/freewheeling diode here, minimizing track length 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 shuts 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 50kΩ, and if the pin is left open V
Input Supply Pin. Must be locally bypassed.
No connection
