CXLE8652是一个2通道LED驱动器，专为电流调节而设计。它可用于各种电流调节电路，特别适用于LED应用。它使led工作在稳定的电流下，避免了电流变化引起的亮度不稳定，同时它的低电压可以降低功耗。VDD电源管脚的连接也可用于通过PWM信号控制led的亮度；因此适合需要亮度调整的应用。REXT引脚的连接可以用来控制输出电流，控制和驱动更多的LED。当REXT打开时，VCH1、VCH2引脚可提供30mA电流。要实现VCH1/VCH2电流超过60毫安的操作，请并联集成电路
•宽工作电源电压范围：2.5V~40V

产品概述 返回TOP
The CXLE8652 is a 2-channel LED driver, designed for current regulation. It may be used in various current regulation circuits, especially suitable for LED applications. It lets LEDs work under stable current and avoid brightness unstable caused by current change, while its low voltage can reduce power consumption. The connection of the VDD power pin may also be used for brightness control of LEDs via PWM signals; therefore suitable for applications that need brightness adjustment. The connection of REXT pin can be used for the control of output current, to control and drive more LEDs. When REXT is open, VCH1, VCH2 pins may provide 30mA of current. To achieve operations with VCH1/VCH2 current over 60mA, connect the ICs in parallel.
