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.
