Block diagram TDA8944J
4-4 TDA835xJ Vertical Amplifier
The TDA835xJ are power circuit for use in 90° and 110° colour deflection systems for field
frequencies of 25 to 200Hz and 16/9 picture tubes. The circuit provides a DC driven vertical
deflection output circuit, operating as a highly efficient class G system. Due to the full bridge
output circuit the deflection coils can be DC coupled.
The IC is constructed in a Low Voltage DMOS process that combines Bipolar, CMOS and
DMOS devices. MOS transistors are used in the output stage because of the absence of second
breakdown.
4-4-1 TDA8357J
Features :
- Few external components
- Highly efficient fully DC-coupled vertical output bridge circuit
- Short rise and fall time of the vertical flyback switch
- Guard circuit
- Temperature (thermal) protection
- High EMC because of common mode inputs
