    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
