2 / 16 page 1998 Sep 03 2 Philips Semiconductors Preliminary specification Full bridge current driven vertical deflection output circuit in LVDMOS 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. QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN.
