The TDA4863 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.
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
• Pb-free lead plating; RoHS compliantImprovements Referred to TDA 4862
• Suitable for universal input applications with low THD at low load conditions
• Very low start up current
• Accurate OVR and VISENSEmax threshold
• Competition compatible VCC thresholds
• Enable threshold referred to VVSENSE
Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
