Product Description

• 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.
