CXLE8115是一款高度集成且经济高效的发光二极管（LED）驱动器，专为LCD显示器和LCD电视背光应用而优化。它提供了一个高性能的LED背光解决方案，以最小化BOM计数。
CXLE8115包含一个使用电流模式控制和固定频率操作来调节LED电流的PWM升压驱动器。LED电流通过外部电流感测电阻器感测。将传感电阻上的电压与参考电压200mV进行比较，放大误差以控制电源开关的脉冲宽度，从而调节流过LED的电流。
CXLE8115为广泛的调光控制提供了外部低频脉宽调制（LPWM）调光方法。CXLE8115提供全面的保护，如功率MOSFET过电流保护（OCP）、输出过电压保护（OVP）、IC电源欠电压锁定（UVLO）和LED开路保护

产品概述 返回TOP
CXLE8115 is a highly integrated and cost effective Light Emitting Diode (LED) driver optimized for LCD monitor and LCD TV backlighting application. It provides a high performance LED backlight solution with minimized BOM count.
The CXLE8115 contains a PWM boost driver which uses current mode control and fixed frequency operation to regulate the LED current. The LED current is sensed through an external current sense resistor. The voltage across the sensing resistor is compared with reference level of 200mV, the error is amplified to control the pulse width of the power switch thus to regulate the current flowing the LED.
The CXLE8115 offers external low frequency PWM (LPWM) dimming method for a wide range of dimming control. The CXLE8115 offers comprehensive protection such as power MOSFET over current protection (OCP), output over voltage protection (OVP), IC power supply under voltage lockout (UVLO), and LED open protection
