Краткое описание:
Synchronous boost 4 x 3 matrix RGB LED driver with I2C and auto animation control
Дополнительная информация
The LP5813 is a synchronous boost 4 x 3 matrix RGB LED driver featuring an autonomous animation engine. It supports an input voltage range of 0.5V to 5.5V, making it suitable for battery-powered applications. The device utilizes a Time-Cross-Multiplexing (TCM) topology to drive up to 12 individual LEDs or 4 RGB LEDs using 4 output pins. It includes an integrated boost converter with programmable output voltage from 3V to 5.5V and 95% efficiency, along with 4 high-precision constant current sinks.
