TDA8357J - Full bridge vertical deflection output

TDA8357J - TDA8357J - Full bridge vertical deflection output circuit in LVDMOS

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

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.
