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 8.25k ?
resistor between RSET and GND to set LED current to 100mA at 100% duty cycle.
Ground.
LED6 driver input. Connect LED anode to VIN and cathode to this pin.
LED5 driver input. Connect LED anode to VIN and cathode to this pin.
LED4 driver input. Connect LED anode to VIN and cathode to this pin.
LED3 driver input. Connect LED anode to VIN and cathode to this pin.
LED2 driver input. Connect LED anode to VIN and cathode to this pin.
LED1 driver input. Connect LED anode to VIN and cathode to this pin.
Heat sink pad. Not internally connected. Connect to ground.
