Description
The STV8172A is a vertical deflection booster
designed for TV and monitor applications.
This device, supplied with up to 35 V, provides up to
3 App output current to drive the vertical deflection
yoke.
The internal flyback generator delivers flyback
voltages up to 75 V.
In double-supply applications, a stand-by state will
be reached by stopping the (+) supply alone.
