Switch Pin. Connect inductor/freewheeling diode here. Minimize trace area at this
pin to reduce EMI.
GND pin
Set Nominal Output Current Pin. To 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 200kΩ, and if the pin is left open V
Input Supply Pin. Must be locally bypassed.
Reserved. Normally connected to Ground
No Connection.
