Function : Vertical Deflection Booster for 2-APP TV (50-60 Hz) Applications
Package : 7-pin Heptawatt Package
Manufactures : STMicroelectronics
The STV9302B ( STV93028 ) is a vertical deflection booster designed for TV (50-60 Hz) applications. This device, supplied with up to 35 V, provides up to 2 App output current to drive the vertical deflection yoke. The internal flyback generator delivers flyback voltages up to 70 V.

1. When DC coupled (see Figure 4), the display vertical position can be adjusted with input bias. On the other hand, 2 supply sources (VS and -VEE) are required.

The device 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.
1. Power amplifier with differential inputs 2. Output current up to 3.8 A (p-p) 3. High vertical deflection frequency up to 200 Hz 4. High linear sawtooth signal amplification 5. Flyback generator: (1) TDA4865J : separate adjustable flyback supply voltage up to 70 V (2) TDA4865AJ : internally doubled supply voltage (two supply voltages only for DC-coupled outputs)
