TDA8350Q
DC-coupled Vertical Deflection and
High EMC immunity due to common mode inputs
Temperature (thermal) protection
East-West output stage with one single conversion
resistor.
2. General Description
The TDA8350Q is a power circuit for use in 90°
and 110° colour deflection systems for field
frequencies of 50 to 120 Hz. The circuit provides
a DC driven vertical deflection output circuit,
operating as a highly efficient class G system and
an East-West driver for sinking the diode
modulator current.
East-West Output Circuit
