Vertical deflection booster
Product specification
TDA4864J; TDA4864AJ
FEATURES
• Power amplifier with differential inputs
• Output current up to 2.5 A (p-p)
• High vertical deflection frequency up to 200 Hz
• High linear sawtooth signal amplification
• Flyback generator:
– TDA4864J: separate adjustable flyback supply
voltage up to 60 V
– TDA4864AJ: internally doubled supply voltage
(two supply voltages only for DC-coupled outputs).
GENERAL DESCRIPTION
The TDA4864J and TDA4864AJ are deflection boosters
for use in vertical deflection systems for frame frequencies
up to 200 Hz.
The TDA4864J needs a separate flyback supply voltage,
so the supply voltages are independently adjustable to
optimize power consumption and flyback time.
For the TDA4864AJ the flyback supply voltage will be
generated internally by doubling the supply voltage and
therefore a separate flyback supply voltage is not needed.
Both circuits provide differential input stages.
