Service manual WP 895/895F, CP885/885F

4-5 TDA835xJ Vertical Amplifier

The TDA835xJ are power circuit for use in 90o and 110o colour deflection systems for field frequencies of 25 to 200Hz 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. MOS transistors are used in the output stage because of the absence of second breakdown.

4-5-1 TDA8357J

Features :

-Few external components

-High efficient fully DC-coupled vertical output bridge circuit

-Short rise and fall time of the vertical flyback switch

-Guard circuit

-Temperature (thermal) protection

-High EMC because of common mode inputs
