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 describes the ratio between active and apparent power is almost one. Line voltage fluctuations can be compensated very efficiently.

TDA4863-2
Overview Pin Definitions and Functions Pin 1 Symbol Description 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. 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. If VVAOUT is less than 2.2 V the gate driver is inhibited. If the current flowing into this pin exceeds an internal threshold the multiplier output voltage is reduced to prevent the MOSFET from overvoltage damage. Multiplier Input MULTIN is the second multiplier input and is connected via a resistive divider to the rectifier output voltage. Current Sense Input ISENSE is connected to a sense resistor controlling the MOSFET source current. The input is internally clamped at -0.3 V to prevent negative input voltage interaction. A leading edge blanking circuitry suppresses voltage spikes when turning the MOSFET on. Zero Current Detector Input DETIN is connected to an auxiliary winding and monitors the zero crossing of the inductor current. Ground Gate Driver Output GTDRV is the output of a totem-pole circuitry for direct driving a MOSFET. Compared with TDA4863 the TDA4863-2 can drive 20A MOSFETS. To achieve this the gate output voltage VGTLat IGT=0A has been set to 0.85 V. An active shutdown circuitry ensures that GTDRV is set to low if the IC is switched off. Positive Voltage Supply If VCC exceeds the turn-on threshold the IC is switched on. When VCC falls below the turn-off threshold the IC is switched off. In switch off mode power consumption is very low. Two capacitors should be connected to VCC. An electrolytic capacitor and 100 nF ceramic capacitor which is used to absorb fast supply current spikes. Make sure that the electrolytic capacitor is discharged before the IC is plugged into the application board.

Functional Description

2.1
Functional Description
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. This occurs near the line voltage peak and causes a high charge current spike with following characteristics: The apparent power is higher than the real power that means low power factor condition, the current spikes are non sinusoidal with a high content of harmonics causing line noise, the rectified voltage depends on load condition and requires a large bulk capacitor, special efforts in noise suppression are necessary. With the TDA4863-2 preconverter a sinusoidal current is achieved which varies in direct instantaneous proportional to the input voltage half sine wave and so provides a power factor near 1. This is due to the appearance of almost any complex load like a resistive one at the AC line. The harmonic distortions are reduced and comply with the IEC555 standard requirements.
2.2
IC Description
The TDA4863-2 contains a wide bandwidth voltage amplifier used in a feedback loop, an overvoltage regulator, an one quadrant multiplier with a wide linear operating range, a current sense comparator, a zero current detector, a PWM and logic circuitry, a totempole MOSFET driver, an internal trimmed voltage reference, a restart timer and an undervoltage lockout circuitry.
2.3
Voltage Amplifier
With an external capacitor between the pins VSENSE and VAOUT the voltage amplifier acts like an integrator. The integrator monitors the average output voltage over several line cycles. Typically the integrators bandwidth is set below 20 Hz in order to suppress the 100 Hz ripple of the rectified line voltage. The voltage amplifier is internally compensated and has a gain bandwidth of 5 MHz (typ.) and a phase margin of 80 degrees. The non-inverting input is biased internally to 2.5 V. The output is directly connected to the multiplier input. The gate drive is disabled when VSENSE voltage is less than 0.2 V or VAOUT voltage is less than 2.2 V. If the MOSFET is placed nearby the controller switching interferences have to be taken into account. The output of the voltage amplifier is designed in a way to minimize these inteferences.

Functional Description
2.4
Overvoltage Regulator
Because of the integrators 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 integrators differential input voltage remains zero during this fast changes a peak current is flowing through the external capacitor into pin VAOUT. If this current exceeds an internal defined margin the overvoltage regulator circuitry reduces the multiplier output voltage. As a result the on time of the MOSFET is reduced.
2.5
Multiplier
The one quadrant multiplier regulates the gate driver with respect of the DC output voltage and the AC half wave rectified input voltage. Both inputs are designed to achieve good linearity over a wide dynamic range to represent an AC line free from distortion. Special efforts have been made to assure universal line applications with respect to a 90 to 270 V AC range. The multiplier output is internally clamped to1.3 V. So the MOSFET is protected against critical operating during start up.
2.6
Current Sense Comparator, LEB and RS Flip-Flop
The source current of the MOS transistor is transferred into a sense voltage via the external sense resistor. The multiplier output voltage is compared with this sense voltage. Switch on time of the MOS transistor is determined by the comparision result To protect the current comparator input from negative pulses a current source is inserted which sends current out of the ISENSE pin every time when VISENSE-signal is falling below ground potential. An internal RC-filter is connected at the ISENSE pin which smoothes the switch-on current spike.The remaining switch-on current spike is blanked out via a leading edge blanking circuit with a blanking time of typ. 200 ns. The RS Flip-Flop ensures that only one single switch-on and switch-off pulse appears at the gate drive output during a given cycle (double pulse suppression).
2.7
Zero Current Detector
The zero current detector senses the inductor current via an auxiliary winding and ensures that the next on-time of the MOSFET is initiated immediately when the inductor current has reached zero. This reduces the reverse recovery losses of the boost converter diode to a minimum. The MOSFET is switched off when the voltage drop of the shunt resistor exceeds the voltage level of the multiplier output. So the boost current waveform has a triangular shape and there are no deadtime gaps between the cycles. This leads to a continuous AC line current limiting the peak current to twice of the average current.
Data Sheet 10 V1.2, 2004-02
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. The timer starts or restarts the TDA4863-2 when the driver output has been off for more than 150 s after the inductor current reaches zero.
2.9
Undervoltage Lockout
An undervoltage lockout circuitry switches the IC on when VCC reaches the upper threshold VCCH and switches the IC off when VCC is falling below the lower threshold VCCL. During start up the supply current is less then 100 A. An internal voltage clamp has been added to protect the IC from VCC overvoltage condition. When using this clamp special care must be taken on power dissipation. Start up current is provided by an external start up resistor which is connected from the AC line to the input supply voltage VCC and a storage capacitor which is connected from VCC to ground. Be aware that this capacitor is discharged before the IC is plugged into the application board. Otherwise the IC can be destroyed due to the high capacitor voltage. Bootstrap power supply is created with the previous mentioned auxiliary winding and a diode (see "Application Circuit" on Page 21).
2.10
Gate Drive
The TDA4863-2 totem pole output stage is MOSFET compatible. An internal protection ciruitry is activated when VCC is within the start up phase and ensures that the MOSFET is turned off. The totem pole output has been optimized to achieve minimized cross conduction current during high speed operation. Compared to TDA4863 a bigger MOS Transistor can be driven by the TDA4863-2. When a big MOSFET is used in applications with TDA4863, for example SPP20N60C3, the falling edge of the gate drive voltage can swing under GND and can cause false triggering of the IC. To prevent false triggering the gate drive voltage of theTDA 4863-2 at low state and gate current IGT= 0mA is set to VGTL= 0.85V (TDA4863: VGTL=0.25V). The difference between TDA4863-2 and TDA4863 is also depicted in diagramm: gate drive voltage low state on page 20.

"Business excellence means intelligent approaches and clearly defined processes, which are both constantly under review and ultimately lead to good operating results. Better operating results and business excellence mean less idleness and wastefulness for all of us, more professional success, more accurate information, a better overview and, thereby, less frustration and more satisfaction."
