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.
Leave floating for normal operation.

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.
Input Supply Pin. Must be locally decoupled to GND with > 2.2μF X7R ceramic capacitor.

Caution: The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore not be
exceeded under any condition.
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

Notes:
2. For most applications the LED current will be within 8% over the duty cycle range specified. Duty cycle accuracy is also dependent on
propagation delay. Smaller size inductors can be used but LED current accuracy may be greater than 8% at extremes of duty cycle. This is
most noticeable at low duty cycles (less than 0.1) or when the input voltage is high and only one LED is being driven.
3. Refer to figure 4 for the device derating curve.
