FUNCTIONAL DESCRIPTION
The vertical driver circuit is a bridge configuration. The
deflection coil is connected between the output amplifiers,
which are driven in opposite phase. An external resistor
(R
internal feed back information. The differential input
circuit is voltage driven. The input circuit has been
adapted to enable it to be used with the TDA9150,
TDA9151B, TDA9160A, TDA9162, TDA8366 and
TDA8367 which deliver symmetrical current signals. An
external resistor (R
differential input determines the output current through
the deflection coil. The relationship between the
differential input current and the output current is defined
by: I
adjustable from 0.5 A (p-p) to 3 A (p-p) by varying R
The maximum input differential voltage is 1.8 V. In the
application it is recommended that V
is recommended because of the spread of input current
and the spread in the value of R
The flyback voltage is determined by an additional supply
voltage V
voltages (class G) makes it possible to fix the supply
voltage V

this method, very high efficiency is achieved.
The supply voltage V
flyback voltage across the coil, this being possible due to
the absence of a decoupling capacitor (not necessary,
due to the bridge configuration). Built-in protections are:
A guard circuit V
activated at the following conditions:
This signal can be used for blanking the picture tube
screen.
An East-West amplifier is also provided. This amplifier is
an inverting amplifier which is current driven. The output
is a current sink.
