TDA4863 overview version 2.1 7 2005-02-18 pin definitions and functions pin symbol description 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 v vaout is connected internally to the first multiplier input. to prevent overshoot the input voltage will be clamped internally at 5 v. input voltage less then 2.2 v inhibits the gate driver. if the current flowing into this pin is exceeding an internal threshold the multiplier output voltage is reduced to prevent the mosfet from overvoltage damage. 3multin multiplier input multin is the second multiplier input and is connected via a resistive divider to the rectifier output voltage. 4 isense 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 direct driving a mosfet. an active shutdown circuitry ensures that gtdrv is low if the ic is switched off. 8vcc positive voltage supply if v cc exceeds the turn-on threshold the ic is switched on. when v cc falls below the turn-off threshold it is switched off and power consumption is very low. an auxilliary winding is charging a capacitor which provides the supply current. a second 100 nf ceramic capacitor should be added to v cc to absorb supply current spikes required to charge the mosfet gate capacitance.

TDA4863 functional description version 2.1 9 2005-02-18 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. 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 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 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 forms 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 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.
TDA4863 functional description version 2.1 10 2005-02-18 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 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 an external sense resistor transfers the source current of the mosfet into a sense voltage.the multiplier output voltage is compared with this sense voltage. 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 v isense -signal is falling below ground potential. the switch-on current peak of the mosfet is blanked out via a leading edge blanking circuit with a blanking time of typically 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 diminishes the reverse recovery losses of the boost converter diode. the mosfet is switched off when the voltage drop of the shunt resistor reaches 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. 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
TDA4863 functional description version 2.1 11 2005-02-18 breakdown, a 0.6 v clamp prevents substrate in jection. 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 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 v cc reaches the upper threshold v cch and switches the ic off when v cc is falling below the lower threshold v ccl . during start up the supply current is less then 100 a. an internal voltage clamp has been added to protect the ic from v cc 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 v cc and a storage capacitor which is connected from v cc 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 totem pole output stage is mosfet compatible. an internal protection ciruitry is activated when v cc is within the start up phase and ensures that the mosfet is turned off. the totem pole output has been optimized to minimize cross conduction current during high speed operation.
