Pin Descriptions
Pin Name

GND
SET
Function
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.
?
Leave floating for normal operation.
(V CTRL = V REF = 1.25V giving nominal average output current I OUTnom = 0.1/R S )
CTRL

Drive to voltage below 0.2V to turn off output current
Drive with DC voltage (0.3V < V CTRL < 1.25V) to adjust output current from 25% to 100% of I OUTnom
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.
V IN
Input Supply Pin. Must be locally decoupled to GND with > 2.2μF X7R ceramic capacitor.

Caution:
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when
handling and transporting these devices
