The LP5813 is a synchronous boost 4 × 3 matrix RGB LED driver with autonomous animation engine control. The device is ideal to support battery-powered applications with 0.5-V to 5.5-V input voltage range, and it has ultra-low normal operation current with 0.4-mA (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 3 V to 5.5 V with 0.1-V 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.

The time-cross-multiplexing (TCM) structure is adopted, which uses 4 output pins to control 12 LED dots individually. Both high-side scan switch and low-side current sink are contained in one output. The total solution size are minimized for space limited system.

The autonomous animation engine can significantly reduce the real-time loading of controller. Each LED can be configured through the related registers to realize vivid and fancy lighting effects. The device can generate 6-MHz clock signal and use it for synchronizing the lighting effects among multiple devices.
