CXLE8948用于驱动LED串(≤50V),通过VC与GND之间的电容器消除AC/DC电源上的100/120Hz电流纹波。如果LED管脚上的电压超过6V,则电流纹波消除功能将被禁用,这有助于限制芯片的功耗。CXLE8948提供短路保护、开路保护和热插拔保护。
最大LED电流内部限制在0.7A。
CXLE8948提供过热保护。当触发OTP时,内部MOSFET关闭,直到温度降到120 oC

产品概述 返回TOP
CXLE8948 is used to drive a LED string (≤50V), and remove the 100/120Hz current ripple on AC/DC power by a capacitor between VC and GND. If the voltage on LED pin exceeds 6V, the current ripple removing function is disabled, which could help limit the power dissipation on chip. CXLE8948 provides short protection, open protection and HOT-PLUG protection.
The maximum LED current is internally limited at 0.7A.
CXLE8948 provides over thermal protection. When OTP is trigged, the internal MOSFET shuts down until the temperature decreases to 120 oC
