1.3 Description

The TDA4863 -2 IC controls a boost converter in a way that sinu soidal 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

Pin Symbol Description

1VSENSE Voltage Amplifier In vertin g 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 inte grat or.

2VAOUT Voltage Amplifier Ou tpu t

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. If the current flowing into

this pin exceeds an internal threshold the multiplier output voltage is

reduced to prevent the MOSFET from overvoltage da mage.

3MULTIN Multiplier Input

MULTIN is the second multiplier input and is connected via a resistive

divider to the rectifier output voltage.

4ISENSE 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 spits when turning the MOSFET on.

5DETIN Zero Current Detector Input

DETIN is connected to an auxiliary winding monitoring the zero

crossing of the inductor current.

6GND Ground

7GTDRV Gate Driver Output

GTDRV is the output of a totem-pole circuitry for dire ct 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 0.85V. An active shutdown circuitry ensures that GTDRV

is set to low if the IC is switched off.

8VCC Positive Voltage Supply

If VCC excees 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 100nF cermanic

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 Des cription

Version 2.1 9 22 Feb 2005

2 Functional Description

2.1 Introduction

Conventional electronic ballasts and switch mode power supplies are designed with a

bridge rectifie r and a bulk capacito r. Their di sadvantage is that the circuit dra ws power

from the line when the i nstantaneous 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 vol tage depends on load condition and requires a la rge

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 th e input voltage hal f sine wave and so provides a power

factor near 1. This is due to th e a ppearanc e of al mo st any comp lex l oad like a resistive

one at the AC line. The harmoni c distortions are reduced and co mply 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 totem-

pole 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 moni tors the average output voltage over several

line cycles. Typically the integra to r´s bandwidth is set be low 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 at 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 Des cription

Version 2.1 10 22 Feb 2005

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. If this current exceeds an internal defined margin the

overvoltage regulator circuitry redu ces 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 are made to assure universal line applications with respect to a 90 to

270 V AC range.

The multiplier output is internally clamped at 1.3 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 determine d by the comparison 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 to 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 miniumum . The MOSFET is sw itched off when the voltage drop of

the shunt resistor reaches the voltage level of the multiplier output. So the boost current

waveform has a triangu lar shape and there are no de adtime gaps between the cycles.

This leads to a continuous AC line current limiting the peak current to twice of the

average current.

TDA4863-2

Functional Des cription

Version 2.1 11 22 Feb 2005

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 µs 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 µA.

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 ca pacitor is discharged before the IC is plug ged into

the application board. Otherwise the IC can be destroyed due to the high capacitor

voltage.

Bootstrap power supply is create d with the previous mentioned auxiliary windi ng 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 traiggering the gate drive voltage of theTDA4863-2

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 the diagram: gate drive

voltage low state on page 20.
