Full bridge current driven vertical deflection
output circuit in LVDMOS
Preliminary specification
TDA8354Q
FEATURES
• Few external components
• Highly efficient fully DC-coupled vertical output bridge
circuit
• Short rise and fall times of the vertical flyback switch
• Guard circuit
• Temperature (thermal) protection
• High ElectroMagnetic Compatibility (EMC) because of
common mode inputs
• Guard signal in zoom mode.
GENERAL DESCRIPTION
The TDA8354Q is a power circuit for use in 90° and 110°
colour deflection systems for field frequencies of
25 to 200 Hz 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, to provide
ruggedness.
