Pin Name

Pin Function

1

EN

PWM Control Pin. This pin is used as a PWM input for dimming of WLEDs. Do not leave floating.

2

GND

Ground.

3

VIN

Voltage Input. Connect at least 1µF ceramic capacitor between VIN and GND.

4

D2

LED2 driver. Connect LED anode to VIN and cathode to this pin. Do not leave floating.

5

RSET

An internal 1.27V reference sets the nominal maximum WLED current. Example, apply a 9.53kΩ

resistor between RSET and GND to set LED current to 30.2mA at 100% duty cycle.

6

D1

LED1 driver. Connect LED anode to VIN and cathode to this pin. Do not leave floating.
