9.1 Application Information

The LP5813 is a 12 LEDs synchronous boost RGB LED driver with autonomous animation engine control. The device is ideal to support battery-powered applications with 0.5V to 5.5V input voltage range. The LP5813 has ultra-low operation current at active mode, and it only consumes 0.4mA when LED current is set at 25mA. In battery powered applications like e-tag, earbud, e-cigarettes, VR headset, RGB mouse, smart speaker, and other handheld devices, LP5813 is ideal to provide premimum LED lighting effects with low power consumption and small package.
