CHEN Jian YAMADAYA Masayuki SHIROYAMA Hironobu
ABSTRACT
LLC current resonant power supply, which is characterized by soft switching, resonance control with a duty ratio of 50% and leakage transformer structure, is suitable for efficiency improvement, noise reduction and profile lowering in switching power supply. Fuji Electric has developed the 2nd generation “FA6A00N Series,” which inherits the characteristics of the 1st generation LLC current resonant control IC, “FA5760N,” and is enhanced with lower standby power and improved protective functions. It integrates the world’s first high-precision secondary side over-load protection function while further reducing the standby power by approximately 20%.
