1A 40V内置功率管LED恒流驱动器

SR5116是一款连续电流模式的降压恒流驱动芯片。在输入电压高于LED电压时，可以有效地用于驱动一颗或多颗串联LED。 SR5116输入电压范围从6V到40V，输出电流可调，最大可达1A。SR5116内置功率开关和一个高端电流采样电路，使用外部电阻设置LED平均电流，并通过VSET引脚接受模拟调光和PWM调光。 软启动的时间可以通过在VSET脚与地之间增加一个外部电容来延长。当VSET脚的电压低于0.3V时，功率开关截止， 进入极低工作电流的待机状态。 采用SOT89-5封装。 ·极少的外部元器件\r\n·宽输入电压范围：从 6V ~ 40V\r\n·高达 1A 的恒电流输出\r\n·单一管脚实现模拟调光和 PWM 调光\r\n·效率高达97.5%\r\n·最大 1MHz 开关频率\r\n· LED 开路保护\r\n·2% 的输出电流精度;
