Description
The STV9326 is a vertical deflection booster
designed for TV and monitor applications.
This device, supplied with up to 30 V, provides up to
3 App output current to drive the vertical deflection
yoke.
The internal flyback generator delivers flyback
Tab connected
voltages up to 65 V.

In double-supply applications, a stand-by state will
be reached by stopping the (+) supply alone.

4 Application Hints
Application Hints
The yoke can be coupled either in AC or DC.
4.1 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 (VS and -VEE) are required.
A Stand-by state will be reached by switching OFF the positive supply alone. In this state, where
both inputs are the same voltage as pin 2 or higher, the output will sink negligible current from the
deviation coil.

4.1.1 Application Hints
For calculations, treat the IC as an op-amp, where the feedback loop maintains V1 = V7.
