UCC3858提供的控制功能的所有必要为积极功率因数校正preregulators需要高效率低权力运作。附近的功率因数控制器实现塑造AC输入电流波形，对应AC输入使用平均电流模式控制的线路电压。UCC3858的运作非常类似于以前设计Unitrode的PFC部分附加功能，让效率更高在轻负载时提高转换器的操作。这是通过线性缩手PWM频率时，输出电压误差放大器下降到低于预定的用户可编程的指示水平在轻负载条件。减少频率缩放充电电流的CT匝道（比例输出功率），并增加死区时间。还有一个瞬时的复位输入拉IC很快折返模式，当负载回来。UCC3858 PWM技术的前沿调制。当结合比较传统的后缘调制下行转换器，这
