S6500P F Semiconductor POWER FACTOR CORRECTION Description This device is power factor correction controller using a discontinues conduction mode of boost converter. Especially, it is optimized for electronic ballasts which prevent abnormal functions in load runaway and feedback loop fault conditions and low power and high density power supplies which require minimum board size. The external component R/C filter is not necessary because the R/C filter is included in current sense block. This is the improved version with a pin out equivalent to world standard.
