DESCRIPTION
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.
