2 / 20 page 1999 Dec 22 2 Philips Semiconductors Product specification Full bridge vertical deflection output circuit in LVDMOS with east-west amplifier TDA8358J FEATURES • Few external components required • High efficiency fully DC coupled vertical bridge output circuit • Vertical flyback switch with short rise and fall times • Built-in guard circuit • Thermal protection circuit • Improved EMC performance due to differential inputs • East-west output stage. GENERAL DESCRIPTION The TDA8358J is a power circuit for use in 90 ° and 110° colour deflection systems for 25 to 200 Hz field frequencies, and for 4 : 3 and 16 : 9 picture tubes. The IC contains a vertical deflection output circuit, operating as a high efficiency class G system. The full bridge output circuit allows DC coupling of the deflection coil in combination with single positive supply voltages. The east-west output stage is able to supply the sink current for a diode modulator circuit. The IC is constructed in a Low Voltage DMOS (LVDMOS) process that combines bipolar, CMOS and DMOS devices. DMOS transistors are used in the output stage because of absence of second breakdown. QUICK REFERENCE DATA SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
