HiperPFS-4 power fac­tor cor­rec­tion ICs en­able ef­fi­cient PFC de­signs

Electronics Bazaar - - New Products -

Power In­te­gra­tions has an­nounced its HiperPFS TM-4 fam­ily of power fac­tor cor­rec­tion (PFC) ICs. The new IC fam­ily serves ap­pli­ca­tions tar­get­ing ef­fi­ciency and power fac­tor per­for­mance at both full load and light load con­di­tions. HiperPFS-4 de­vices in­cor­po­rate a 600V MOSFET suit­able for 305V AC in­put and is a high ef­fi­ciency, vari­able fre­quency, CCM PFC con­troller in a sin­gle, com­pact, elec­tri­cally iso­lated, heat sink­able pack­age. HiperPFS-4 ICs achieve a high power fac­tor of above 0.95 and low THD even at 20 per cent of the rated load. The de­vices also meet the strin­gent surge re­quire­ments of ma­jor com­puter and en­ter­tain­ment equip­ment providers, such as the 1 se­cond 410V AC in­put test, which en­sures field re­li­a­bil­ity and ro­bust­ness against volt­age swells and surges.
