9.2.5
IC301
The STV8172A is a vertical deflection booster designed for TV
and monitor applications. This device, supplied with up to 35 V,
provides up to 2.5 A output current to drive the vertical
deflection yoke.
The internal fly back generator delivers fly back voltages up to
75 V. In double-supply applications, a stand-by state will be
reached by stopping the (+) supply alone.
