4.3 VERTICAL SCAN OUTPUT STAGE CIRCUIT
TDA4864AJ
4.3.1 FEATURES
TDA4864AJ: Output current up to 2.5A (p-p)
4.3.2 GENERAL DESCRIPTION
The TDA4864AJ is deflection boosters for use in vertical deflection systems for frame frequencies up to
200 Hz.
The TDA4864AJ needs a separate flyback supply voltage, so the supply voltages are independently adjustable
to optimize power consumption and flyback time.
For the TA4864AJ the flyback supply voltage will be generated internally by doubling the supply voltage
and therefore a separate flyback supply voltage is not needed.
