采用集成600 V MOSFET的PFC控制器可在整个负载范围内提供高功率因数，具有高效率

HiperPFS™-4器件将一个连续导通模式(CCM)升压PFC控制器、栅极驱动器和600V功率MOSFET集成在一个（接地引脚内部相连）薄型功率封装中。HiperPFS-4器件可省去外部电流检测电阻，从而避免与其相关的功率损耗。其创新的控制技术，可在整个输出负载、输入电压和输入工频周期内调整开关频率。\n 这项控制技术能够提高整个负载范围内的效率，特别是轻载条件下的效率。此外，由于其很宽的带宽频谱分布效应，可以降低对EMI滤波的要求。HiperPFS-4采用先进的数字技术来实现输入电压监测、输入电压前馈调节和功率因数改善，同时核心控制器采用模拟技术来维持极低的空载功耗。\n Hi • 在整个负载范围内均具有高效率及高功率因数\r\n• 提供集成600V二极管的型号(PFS77xx)\r\n• 数字式输入电压峰值检测 - 即使在不间断电源(UPS)或发电机供电时产生的电压出现畸变情况下仍可提供可靠性能\r\n• 在>60kHz的频率范围内进行频谱分散，可简化EMI滤波\r\n• 可耐受305VAC稳态和410VAC异常输入电压\r\n• 无需绝缘垫片/导热散热片;
