CXAC85182

CXAC85182是一个升压转换器,设计用于驱动多达8个系列的白色LED用于背光应用。CXAC85182采用电流模式,1.2兆赫固定频率结构来调节LED电流,该电流通过外部电流感测电阻器设置。它的低300毫伏反馈电压降低了功率损耗,提高了效率。如果由于开路而出现过电压情况,则OV引脚监测输出电压并关闭转换器。CXAC85182包括欠压锁定、限流和热关机保护,防止输出过载时损坏。

The CXAC85182 is a step-up converter designed for driving up to 8 series white LEDs for backlighting application. The CXAC85182 uses current mode, 1.2MHZ fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor. Its low 300mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The CXAC85182 includes under-voltage lockout, current limiting and thermal shutdown protection preventing damage in the event of an output overload. The driver is available in small 6-pin SOT-23 package.
