The input voltage range is 6V to 55v, and the maximum output current is 1.2A. Cxle8836 is equipped with built-in power switch and high-end current detection circuit. LED current is set by external resistance. It can receive analog dimming and PWM dimming through adj pin. When adj is less than 0.2V, it will enter into low-power standby mode. Cxle8836 is equipped with over temperature automatic regulation function. When overheat of driving power is detected, the output current is automatically reduced gradually, so as to control the output power and temperature rise, so as to keep the temperature of driving power within the set value range, so as to improve the reliability of the system.

产品概述 返回TOP
CXLE8836是一款连续电流模式的降压恒流驱动芯片。在输入电压高于LED电压时，可以有效地用于驱动一颗或多颗串联LED。输入电压范围从6V到55V，输出电流最大可达 1.2A。 CXLE8836 内置功率开关和高端电流检测电路， 使用外部电阻设置 LED 电流，可通过ADJ引脚接 收模拟调光和PWM调光，当ADJ小于0.2V后将进入低功耗待机模式。 CXLE8836置过温自动调节功能。当检测到驱动电源过热时，即自动逐渐减小输出电流，从而控制输出功率和温升，使驱动电源温度保持在设定值范围内，从而提高系统的可靠性。芯片内部过温调节阈值设定为 150℃。
