STV93028 datasheet

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.


STV93028 pinout


1. Power Amplifier
2. Flyback Generator
3. Output Current up to 2 App
4. Thermal Protection

DC-coupled Application

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.

TDA4865AJ datasheet



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)


TDA4865AJ pinout

VP1 : 1 ( positive supply voltage 1 )
VFB : – ( flyback supply voltage )
VP3 : 2 ( flyback generator output )
VP2 : 3 ( supply voltage 2 for vertical output )
GND : 4 ( ground or negative supply voltage )
VOUT : 5 ( vertical output )
INN : 6 ( inverted input of differential input stage )
INP : 7 ( non-inverted input of differential input stage )
