TDA4863-2 Overview AC line RF-Filter and Rectifier DC Output Volage TDA4863-2 GND Figure 1 1.3 Typical application 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.

TDA4863-2 Overview Pin Definitions and Functions Pin Symbol 1 VSENSE Voltage Amplifier Inverting Input VSENSE is connected via a resistive divider to the boost converter output. With a capacitor connected to VAOUT the internal error amplifier acts as an integrator. 2 VAOUT Voltage Amplifier Output VVAOUT is connected internally to the first multiplier input. To prevent overshoot the input voltage is clamped internally at 5 V. IfVVAOUT is less then 2.2 V the gate driver is inhibited.

TDA4863-2 Functional Description 2 Functional Description 2.1 Introduction Conventional electronic ballasts and switch mode power supplies are designed with a bridge rectifier and a bulk capacitor. Their disadvantage is that the circuit draws power from the line when the instantaneous AC voltage exceeds the capacitors voltage.
PAGE 10
TDA4863-2 Functional Description 2.4 Overvoltage Regulator Because of the integrator´s low bandwidth fast changes of the output voltage can’t be regulated within an adequate time. Fast output changes occur during initial start-up, sudden load removal, or output arcing. While the integrator´s differential input voltage remains zero during this fast changes a peak current is flowing through the external capacitor into pin VAOUT.
PAGE 11
TDA4863-2 Functional Description To prevent false tripping the zero current detector is designed as a Schmitt-Trigger with a hysteresis of 0.5 V. An internal 5 V clamp protects the input from overvoltage breakdown, a 0.6 V clamp prevents substrate injection. An external resistor has to be used in series with the auxiliary winding to limit the current through the clamps. 2.8 Restart Timer The restart timer function eliminates the need of an oscillator.
