Product speciﬁcation

Vertical deﬂection booster

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.
