Functional Description
Functional Description
Introduction
Conventional electronic ballasts switch mode power supplies designed with bridge rectifier bulk capacitor. Their disadvantage that circuit draws power from line when instantaneous voltage exceeds capacitors voltage. This occurs near line voltage peak causes high charge current spike with following characteristics: apparent power higher than real power that means power factor condition, current spikes sinusoidal with high content harmonics causing line noise, rectified voltage depends load condition requires large bulk capacitor, special efforts noise suppression necessary. With TDA4863 preconverter sinusoidal current achieved which varies direct instantaneous proportional input voltage half sine wave provides power factor near This appearance almost complex load like resistive line. harmonic distortions reduced comply with IEC555 standard requirements.
Description
TDA4863 contains wide bandwidth voltage amplifier used feedback loop, overvoltage regulator, quadrant multiplier with wide linear operating range, current sense comparator, zero current detector, logic circuitry, totempole MOSFET driver, internal trimmed voltage reference, restart timer undervoltage lockout circuitry.
Voltage Amplifier
With external capacitor between pins VSENSE VAOUT voltage amplifier acts like integrator. integrator monitors average output voltage over several line cycles. Typically bandwidth below order suppress ripple rectified line voltage. voltage amplifier internally compensated gain bandwidth (typ.) phase margin degrees. non-inverting input biased internally output directly connected multiplier input. gate drive disabled when VSENSE voltage less than VAOUT voltage less than MOSFET placed nearby controller switching interferences have taken into account. output voltage amplifier designed minimize these inteferences.

Functional Description
Overvoltage Regulator
Because bandwidth fast changes output voltage can't regulated within adequate time. Fast output changes occur during initial start-up, sudden load removal, output arcing. While differential input voltage remains zero during this fast changes peak current flowing through external capacitor into VAOUT. this current exceeds internal defined margin overvoltage regulator circuitry reduces multiplier output voltage. result time MOSFET reduced.
Multiplier
quadrant multiplier regulates gate driver with respect output voltage half wave rectified input voltage. Both inputs designed achieve good linearity over wide dynamic range represent line free from distortion. Special efforts have been made assure universal line applications with respect range. multiplier output internally clamped to1.3 MOSFET protected against critical operating during start
Current Sense Comparator, Flip-Flop
source current transistor transferred into sense voltage external sense resistor. multiplier output voltage compared with this sense voltage. Switch time transistor determined comparision result protect current comparator input from negative pulses current source inserted which sends current ISENSE every time when VISENSE-signal falling below ground potential. internal RC-filter connected ISENSE which smoothes switch-on current spike.The remaining switch-on current spike blanked leading edge blanking circuit with blanking time typ. Flip-Flop ensures that only single switch-on switch-off pulse appears gate drive output during given cycle (double pulse suppression).
Zero Current Detector
zero current detector senses inductor current auxiliary winding ensures that next on-time MOSFET initiated immediately when inductor current reached zero. This reduces reverse recovery losses boost converter diode minimum. MOSFET switched when voltage drop shunt resistor exceeds voltage level multiplier output. boost current waveform triangular shape there deadtime gaps between cycles. This leads continuous line current limiting peak current twice average current.

Functional Description prevent false tripping zero current detector designed Schmitt-Trigger with hysteresis internal clamp protects input from overvoltage breakdown, clamp prevents substrate injection. external resistor used series with auxiliary winding limit current through clamps.
Restart Timer
restart timer function eliminates need oscillator. timer starts restarts TDA4863 when driver output been more than after inductor current reaches zero.
Undervoltage Lockout
undervoltage lockout circuitry switches when reaches upper threshold VCCH switches when falling below lower threshold VCCL. During start supply current less then internal voltage clamp been added protect from overvoltage condition. When using this clamp special care must taken power dissipation. Start current provided external start resistor which connected from line input supply voltage storage capacitor which connected from ground. aware that this capacitor discharged before plugged into application board. Otherwise destroyed high capacitor voltage. Bootstrap power supply created with previous mentioned auxiliary winding diode (see "Application Circuit" Page 21).
