CXLE8945 CXLE8946用于驱动小于60V的LED串，通过VC与GND之间的电容器消除交直流电源上的100/120Hz电流纹波。CXLE8945允许用户通过在VLMT和GND之间连接一个电阻器来设置LED管脚上的最大电压。如果LED管脚上的电压超过极限阈值，则电流纹波消除器将被禁用并保持LED电压，这有助于限制芯片上的功耗。多个JCXLE8945可以通过将所有VC管脚短接在一起并行工作。每个CXLE8945之间的平均电流匹配率小于±1%。最大LED电流内部限制为440毫安。CXLE8945提供热保护

产品概述 返回TOP
CXLE8945 CXLE8946 is used to drive a LED string (＜60V), and remove the 100/120Hz current ripple on AC/DC power by a capacitor between VC and GND. CXLE8945 allows user to setup the maximum voltage on LED pin by connect a resistor between VLMT and GND. If the voltage on LED pin exceeds limit threshold, the current ripple remover is disabled and remain the LED voltage, which could help limiting the power dissipation on chip. Multiple JCXLE8945 can operate in parallel by shorting all VC PINs together. The average current matching rate between each CXLE8945 is less than ±1%. The maximum LED current is internally limited as 440mA. CXLE8945provides thermal protection
