Cxle8295 is a continuous on mode inductive step-down converter designed to drive single or multiple series connected high efficiency LEDs from one voltage source to the total led chain voltage. The device operates 32V from an input power supply between 8V and provides adjustable output current up to 1a. Depending on the power supply voltage and external components, the cxle8295 provides more than 15 watts of output power. The cxle8295 includes a power switch and a high side output current sensing circuit, which uses an external resistor to set the nominal average output current, and the dim pin receives a large range of pulse dimming. Apply a voltage of 0.3V or as low as the dim pin to turn off the output and switch the device to the low current standby state

产品概述 返回TOP
CXLE8295是一个连续导通模式电感降压转换器，专用于驱动连接的单个或多个串联从一个电压源高效率LED比总LED链电压。 该设备从8V之间的输入电源工作32V，并提供高达1A的输出电流可调。 这取决于电源电压和外部元件，CXLE8295可提供超过15瓦特输出功率。 CXLE8295包括电源开关和一个高侧的输出电流传感电路，它使用一个外部电阻器来设定标称平均输出电流，并且DIM引脚接受一个大范围的脉冲调光。 施加0.3V的电压或低到DIM引脚关掉输出，并切换装置进入低电流待机状态。该CXLE8295可在SOT89-5L封装
