白光LED驱动

\nLN2117系列是一款固定频率、恒定电流的升压DC/DC 控制器,主要用于手机、PDA和数码相机等设备上的白光背光LED驱动。输出电压最高可以达到20 V，输入电压为3.0V时能驱动6个LED串联，LED的亮度可以外加一个PWM信号来控制。电路内部集成了一个内阻2欧姆的大管子，外部只要采用0.22uF的电容，减小了外围电路的面积，LN2117的B系列带过压保护功能。 ·输入电压：2.5V—6V \n·输出电压： 最大可以达到20V \n·振荡频率： 1MHz±20% \n·效率： 88%（输入电压为3.6V驱动3个串联的LED，LED电流为20mA） \n·工作控制模式： PWM控制的电流模工作模式 \n·待机功耗： 最大1.0μA \n·负载电容： 0.22μF，陶瓷电容 \n·LX端电流限制 300mA;

SINGLE CHANNEL DRIVER

SINGLE CHANNEL DRIVER The MPIC2117 is a high voltage, high speed, power MOSFET and IGBT driver. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS outputs. The output drivers feature a high pulse current
