FUNCTIONAL DESCRIPTION
The vertical driver circuit is a bridge configuration. The
deflection coil is connected between the output amplifiers,
which are driven in phase opposition. An external resistor
(R
M
) connected in series with the deflection coil provides
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
CON
) connected between the 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
diff
×
R
CON
= I
(coil)
×
R
M
.
The output current is adjustable from 0.5 A (p-p) to 3 A
(p-p) by varying R
M
. The maximum input differential
voltage is 1.8 V. In the application it is recommended that
V
diff
= 1.5 V (typ). This is recommended because of the
spread of input current and the spread in the value of
R
CON
.
The flyback voltage is determined by an additional supply
voltage V
FB
. The principle of operating with two supply
voltages (class G) makes it possible to fix the supply
voltage V
P
optimum for the scan voltage and the second
supply voltage V
FB
optimum for the flyback voltage. Using
this method, very high efficiency is achieved.
The supply voltage V
FB
is almost totally available as
flyback voltage across the coil, this being possible due to
the absence of a decoupling capacitor (not necessary, due
to the bridge configuration). The output circuit is fully
protected against the following:
thermal protection
short-circuit protection of the output pins (pins 5 and 9)
short-circuit of the output pins to V
P.
A guard circuit V
O(guard)
is provided. The guard circuit is
activated at the following conditions:
during flyback
during various short-circuit possibilities at the output
pins
during open loop
when the thermal protection is activated.
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 with sink
current only capabilities.
