8.1 Application Information

The LP5817 is a 3 channel RGB LED driver. The device has ultra-low operation current at active mode and only consumes 0.25mA when LED current is set at 25mA. In battery powered applications like e-tag, ear bud, e-cigarettes, VR headset, RGB mouse, smart speaker, and other hand-held devices, LP5817 can provide premium LED lighting effects with low power consumption and small package.
