ICs enable 98% efficiency of power factor correction


POWER INTEGRATIONS HiperPFSTM-4 family of power factor correction (PFC) ICs serve applications targeting improved efficiency and power factor performance at both full load and light load conditions. Devices incorporate a 600V MOSFET suitable for 305Vac input and a high efficiency, variable frequency, CCM PFC controller in a single, compact, electrically isolated, heatsinkable package. Product family delivers high power factor, low THD and uniformly high efficiency across a wide output load range. http://www.power.com
