【产品】亚成微电子推出高精度高压线性LED恒流控制芯片RM9001DB,具备过温调控、功率补偿功能
亚成微推出的RM9001DB是一款采用自适应LED四段分段驱动机制的高精度高压线性LED恒流控制芯片,可以灵活设置每段LED串,适应不同地区的市电电压,LED的利用率和总输出流明数高。
RM9001DB可以通过外部电阻调整LED电流,通过控制分段导通LED电流,可以提高整体方案PF,同时RM9001DB可以满足IEC61000-3-2照明设备C类谐波标准要求。
RM9001DB具备可调节的过温调控功能。当应用方案输入电压超过应用电压,芯片内部的过温调控功能会降低输出电流,维持整体功率稳定。
RM9001DB芯片具备功率补偿功能,在输出电压升高的情况下,芯片会通过外置补偿电阻调整LED补偿电流保证输入功率基本不变。
