Cxle86186 is a constant current drive chip with continuous current mode. When the input voltage is higher than the LED voltage, it can be effectively used to drive one or more LEDs

Cxle86186 is a constant current drive chip with continuous current mode. When the input voltage is higher than the LED voltage, it can be effectively used to drive one or more LEDs in series. The input voltage range of cxle86186 is from 6V to 40V, and the output current is adjustable up to 1 Amp. The cxle86186 has a built-in power switch and a high-end current detection circuit. It uses an external resistance to set the average current of the LED, and receives the analog dimming and PWM dimming through the adj pin. The chip contains a PWM filter circuit, which controls the rising edge of the current to realize the soft start function. The soft start time can be extended by adding an external capacitance between the adj pin and the ground. When the voltage of adj is lower than 0.2V, the power switch is cut off, and mcxle86186 enters the standby state of very low working current

       CXLE86186 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。CXLE86186 输入 电压范围从 6 伏到 40 伏,输出电流可调,最大 可达 1 安培。 CXLE86186 内置功率开关和一个高端电流检测电 路,使用外部电阻设置 LED 平均电流,并通过 ADJ 引脚接收模拟调光和 PWM 调光。芯片内含 有 PWM 滤波电路,PWM 滤波电路通过控制电流的 上升沿从而实现软启动的功能。软启动的时间可 以通过在 ADJ 脚与地之间增加一个外部电容来 延长。当 ADJ 的电压低于 0.2 伏时,功率开关截 止,MCXLE86186进入极低工作电流的待机状态。 CXLE86186采用 SOT89-5 封装。
