Cxle87167a is a step-down LED constant current driver working in inductive current continuous mode It is used to drive one or more series LED efficiently The input voltage range of the chip is 5V~36V

Cxle87167a is internally integrated with power tube and adopts high-end current detection mode. The average current of LED output can be set through the external resistance, and the analog dimming and PWM dimming signals with a wide range can be received through the dim pin. When the voltage of dim is lower than 0.3V, the power tube inside the chip turns off, and cxle87167a enters the standby mode with low power consumption.

     CXLE87167A 是一款工作在电感电流连续模式下的降压型 LED 恒流驱动器。用于高效地驱动一颗或者多颗串联 LED。芯 片的输入电压范围为 5V~36V,输出电流外部可调,最大可 达 1.2A。 CXLE87167A 内部集成功率管,并采用高端电流检测方式。通过 外部电阻可以设定 LED 输出的平均电流,并可以通过 DIM 引脚接收模拟调光和很宽范围的 PWM 调光信号。当 DIM 的电压低于 0.3V,芯片内部的功率管关断,CXLE87167A进入 低功耗的待机模式。 CXLE87167A内部集成了自动温度补偿控制电路,当芯片内部的 温度超过 130℃时,LED 输出电流会随着温度的上升而逐 渐减小,并最终稳定在某一电流值。这就避免了传统过温 保护所引起的 LED 低频闪烁问题。当芯片内部的温度上升 到 150℃时,LED 输出电流减小至零。
