Pin Function
LED Dimming Current Set:
Connect a resistor-to-GND to set the dimming current from 15mA to 30mA. Use 2kΩ for 30mA,
and 3kΩ for 20mA.
Capacitor reference voltage: Connect a 2.2µF capacitor-to-GND.
Analog signal Ground.
LED Channel Current Sinker:
Connect the cathode of each channel of LEDs to one current sinker.
No Connect.
Power Ground.
Switch Node: Internal power NPN collector.
Enable Pin: Connect HIGH or LOW; do not float.
Supply: 6V to 40V.
Output of internal LDO:
Connect a 10µF capacitor-to-GND.
Connect to PGND
