Product Summary

The TDA4863AJ is a deflection booster for use in 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. Both circuits provide differential input stages and fit well with the TDA485X monitor deflection controller family.
