   产品概述 返回TOPh3F嘉泰姆

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.
