Краткое описание:
Synchronous Boost 4-Channel RGBW LED Driver with Autonomous Control
Дополнительная информация
The LP5811 is a high-efficiency synchronous boost 4-channel RGBW LED driver designed for battery-powered applications. It features an integrated boost converter with an output range of 3V to 5.5V and supports an input voltage as low as 0.5V. The device includes four high-precision constant current sinks (up to 51mA each) with ultra-low headroom voltage and an autonomous animation engine to reduce MCU load.
