Pin Function
Voltage Input. Connect at least 2.2μF ceramic capacitor between VIN and GND.
Enable LED drivers. This pin can be used as a PWM input for dimming of WLEDs. Do not leave
floating.
An internal 1.27V reference sets the nominal maximum WLED current. Example, apply a 6.19k ?
resistor between RSET and GND to set LED current to 830mA at 100% duty cycle.
Ground.
LED1 driver input. Connect LED anode to VIN and cathode to this pin. All D1 pins must be
connected to the LED.
