GENERAL DESCRIPTION
The TDA8357J 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 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.

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.
