TDA4863

Fully compatible with the world standard, TDA4863 is optimized to offer extremely compact and cost effective PFC solutions for electronic ballast and off-line SMPS. By using a zero current detector for discontinuous operation mode a near unity power factor and an excellent THD are achieved. | Summary of Features: High power factor Power; Controls boost converter as active harmonic filter for low THD; Start up with low current consumption; Zero current detector for discontinuous conduction mode; Output overvoltage protection; Output undervoltage lockout; Internal start up timer; Totem pole output with active shut down; Internal leading edge blanking LEB; Improvements of TDA4863 to TDA4862:; Very low start up current; Very low comparator and multiplier offsets for universal input applications; High sophisticated amplifier for low distortion inteferences caused by MOSFET switching; Accurate overvoltage threshold
