S6500

회ㅏ F Semiconductor S6500 POWER FACTOR CORRECTOR 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. Features Dynamic, Static & Feedback OVP Extremely Low Start up Current (30uA Typ.) Very Low Operating Current (4mA Typ.) Internal Self Start Timer Current Sense with Internal RC Filter Trimmed ±1.5% internal Reference Under Voltage Lock Out with Hysteresis Pin Compatible to World Standard High Current Totem Pole Gate Drive Applications Electronic Ballast SMPS Ordering Information Type NO.
