Pin Function
Serial Control Digital input. Do not leave floating.
Ground.
Voltage Input. Connect at least 1µF ceramic capacitor between VIN and GND.
LED2 driver. Connect LED anode to VIN and cathode to this pin. Do not leave floating.⁽¹⁾
Connect an external resistor from this pin to GND to set the maximum LED current. Example,
apply a 9.53kΩ resistor between RSET and GND to set LED current to 30mA at 100% duty
cycle.
LED1 driver. Connect LED anode to VIN and cathode to this pin. Do not leave floating. ⁽¹⁾
Note 1. When driving only 1 LED, connect D1 and D2 in parallel to the LED cathode and adjust the RSET resistor for half the desired output.
