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.
