CXLE8947 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. CXLE8947 provides short protection, open protection and HOT-PLUG protection. 

The maximum LED current is internally limited at 1.6A. gEf嘉泰姆

CXLE8947 provides over thermal protection. When the OTP is trigged, the internal MOSFET shuts down until the temperature decreases to 120℃.gEf嘉泰姆
