功率因数控制器，增强型，高能效

The NCP1612 is active power factor corrected (PFC) controller specifically designed for use as a boost pre-converter in ac-dc adapters, flat TVs, lighting ballasts and other medium powered offline applications. The controller is based on an innovative Current Controlled Frequency Foldback(CCFF) meth • Critical conduction mode with current controlled frequency foldback\n• Optimizes conversion efficiency across load range\n• Dynamic Response Enhancer\n• Improved transient response for line and load steps\n• Soft Overvoltage Protection\n• Reduces accoustic noise and stress in the event of an overv;
