Vertical deflection booster TDA4863J; TDA4863AJ
FEATURES
• Power amplifier with differential inputs
• Output current up to 3 A (p-p)
• High vertical deflection frequency up to 200 Hz
• High linear sawtooth signal amplification
• Flyback generator:
– TDA4863J: separate adjustable flyback supply
voltage up to 60 V
– TDA4863AJ: internally doubled supply voltage
GENERAL DESCRIPTION
The TDA4863J and TDA4863AJ are deflection boosters
for usein vertical deflection systems for frame frequencies
up to 200 Hz.
The TDA4863J needs a separate flyback supply voltage,
so the supply voltages are independently adjustable to
optimize power consumption and flyback time.
For the TDA4863AJ the flyback supply voltage will be
generated internally by doubling the supply voltage and
therefore a separate flyback supply voltage is not needed.
(two supply voltages only for DC-coupled outputs).
Both circuits provide differential input stages and fit well
with the TDA485X monitor deflection controller family.

FUNCTIONAL DESCRIPTION
Both the TDA4863J and TDA4863AJ consist of a
differential input stage, a vertical output stage, a flyback
generator, a reference circuit and a thermal protection
circuit.
The TDA4863J operates with a separate flyback supply
voltage (see Fig.1) while the TDA4863AJ generates the
flyback voltage internally by doubling the supply voltage
(see Fig.2).
Differential input stage
Thedifferential sawtoothinputsignal (e.g.comingfrom the
deflection controller family TDA485X) is connected to the
inputs (inverted signal to pin 6 and non-inverted signal to
pin 7). The vertical feedback signal is superimposed on
the inverted signal on pin 6.
Vertical output and thermal protection
The vertical output stage is a quasi-complementary
class-B amplifier with a high linearity.
The outputstage is protected againstthermal overshoots.
For a junction temperature Tj> 150 °C this protection will
be activated andwill reducethen thedeflection current(I5).
Flyback generator
The flyback generator supplies the vertical output stage
during flyback.
The TDA4863J is used with separate flyback supply
voltage to achieve a short flyback time with minimized
power dissipation.
The TDA4863AJ needs a capacitor CF between
pins 2 and 3 (see Fig.2). Capacitor CF is charged during
scan, using the external diode D1 and resistor R5. During
flyback the cathode of capacitor CF is connected to the
positive supply voltage and the flyback voltage is then
twice the supply voltage. For the TDA4863AJ the
resistor R6 in the positive supply line can be used to
reduce the power consumption.
In parallel with the deflection coil a damping resistor R
and an RC combination (RS1= 5.6 Ω and CS1= 100 nF)
are needed. Furthermore, another additional
RC combination (RS2= 5.6 Ω and CS2= 47 to 150 nF)
can be used to minimize the noise effect and the flyback
time (see Figs 9 and 10).
