Description
The STV9302A is a vertical deflection booster
designed for TV and monitor 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.
in double-supply applications, a stand-by state will
be reached by stopping the (+) supply alone.

    STV9302A Application Hints Application Hints The yoke can be coupled either in AC or DC. DC-coupled Application When DC coupled (see Figure 4), the display vertical position can be adjusted with input bias. On the other hand, 2 supply sources (V and -V ) are required.

  • Page 7 STV9302A Application Hints AC-Coupled Applications In AC-coupled applications (See Figure 6), only one supply (V ) is needed. The vertical position of the scanning cannot be adjusted with input bias (for that purpose, usually some current is injected or sunk with a resistor in the low side of the yoke).
