Pin Function
Voltage Input. Connect at least 1µF 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 20.5kΩ
resistor between RSET and GND to set LED current to 20mA at 100% duty cycle.
Ground.
No Connect. This pin is not connected internally.
No Connect. This pin is not connected internally.
LED4 driver. Connect LED anode to VIN and cathode to this pin.
LED3 driver. Connect LED anode to VIN and cathode to this pin.
LED2 driver. Connect LED anode to VIN and cathode to this pin.
LED1 driver. Connect LED anode to VIN and cathode to this pin.
Heat sink pad. Not internally connected. Connect to ground.
