Power Factor Correction CONTRLR 0.02mA 8-Pin DSO

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.

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
