Description

General part information

LP5811 Series

The LP5811 is a synchronous boost 4-channel RGBW 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, and it has ultra-low normal operation current with 0.4mA (typical) when illuminate LEDs.

The integrated synchronous boost converter maintains excellent efficiency and keeps the brightness of LEDs stable over a wide operating voltage range. Output voltage can be selected for different LED forward voltage from 3V to 5.5V with 0.1V step. The boost converter can power not only the LEDs driven by the device itself, but also other loads in the system. If the boost converter need to be bypassed, VOUT is used as the power supply input for the LED driver blocks.

Both analog dimming and PWM dimming methods are adopted to achieve powerful dimming performance. The output current of each LED can be adjusted with 256 steps from 0.1mA to 25.5mA or 0.2mA to 51mA. The 8-bit PWM generator enables smooth and audible-noise-free dimming control for LED brightness.
