TDA4863G Datasheet

Power Factor Correction ICs


The TDA4863G IC controls a boost converter in a way that sinusoidal current is taken from the single phase line supply and stabilized DC voltage is available at the output. This active harmonic filter limits the harmonic currents resulting from the capacitor pulsed charge currents during rectification. The power factor which describes the ratio between active and apparent power is almost one. Line voltage fluctuations can be compensated very efficiently. TDA4863G Features • IC for sinusoidal line-current consumption• Power factor achieves nearly 1• Controls boost converter as active harmonic filter for low THD• Start up with low current consumption• Zero current detector for discontinuous operation mode• Output overvoltage protection• Output undervoltage lockout• Internal start up timer• Totem pole output with active shut down• Internal leading edge blanking LEB
