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.
