恒流二极管

TM1910-X是高精度的单通道LED恒流驱动芯片，不需要增加外部电阻设定电流大小，输出电流大小可在5~65/12mAf范围内选择。芯片具有极低的恒流输出转折压降，具有宽的输入电压范围，具有极高的恒流输出精度和恒流输出稳定度。芯片具有过温保护功能，当芯片结温达到135℃时，随着芯片温度继续上升，芯片会线性降低输出电流。TM1910-X芯片质量可靠，性能优秀，在各种LED照明产品中非常简单易用。 \n• 单通道恒流LED驱动\n• 5~65mA、120mA,14档恒定输出电流选择，无需外部电阻设定电流\n• 宽输入电压范围：5V~24V\n• 电源转换效率高达98%\n• 超低drop-out压降(20mA驱动时，低至300mV)\n• ±5%输出电流精度\n• 电源及负载调变率0.1%/V\n• 芯片工作温度-40~125℃\n• 具有芯片过温保护功能\n• SOT23-3，SOT-89无铅环保封装;
