Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.
2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and
Lead-free.
3. Halogen and Antimony free "Green‖ products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl)
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.
Dual function dimming control pin.
Input voltage of 0.2V or lower forces the device into low current standby mode and
shuts off the output.
A PWM signal (driven by an open-drain/collector source) allows the output current
to be adjusted over a wide range up to 100%.

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.
