3. Quick reference data
The TDA4865J and TDA4865AJ are deflection boosters for use in vertical deflection
systems for frame frequencies up to 200 Hz.
The TDA4865J needs a separate flyback supply voltage, so the supply voltages are
independently adjustable to optimize power consumption and flyback time.
For the TDA4865AJ 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.
