Boost Controller TDA4863-2/TDA4863-2G Power-Factor Controller (PFC)IC for High Power Factor and Low THD

Overview

TopologyOther Topology
IC revision2

Description

The TDA4863-2 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 decibels the ratio between active and apparent power is almost one. Line voltage fluctuations can be compensated very efficiently.

Features

  • IC for sinusoidal line-current consumption
  • Power factor achieves nearly 1
  • Controls boost converter as active harmonicfilter for low THD
  • Start up with low current consumption
  • Zero current detector for discontinuousoperation mode
  • Output overvoltage protection
  • Output undervoltage lockout
  • Internal start up timer
  • Totem pole output with active shut down
  • Internal leading edge blanking LEB
  • Pb-free lead plating ; RoHS compliant
