Cxac8519 series is a control chip specially designed for power factor correction. It is mainly designed for switching power supply, adapter and charger within 300W. Very high PF value and small thd can be easily achieved in the full voltage range. The internal multiplier has the optimized thd special circuit, which can effectively control the AC input current crossing distortion and the error amplifier output ripple distortion, so as to improve the power factor and reduce the thd
