Color TV Vertical Deflection Output Circuit
Overview
The LA7833 is a monolithic linear IC for vertical deflection
output for large color television sets that requires few external
components and dissipates little power. When used in
conjunction with the LA7620 series of video chroma deflection
ICs, the LA7800 series of deflection ICs, and the LA7850
series of display ICs, it is possible to create a stable and
compact vertical output deflection circuit.
Features
.
High output.
.
Low power dissipation due to built-in pump-up circuit.
.
Few external components needed.
.
Thermal protection circuit built in.
