Overview
The LA7835 is an IC that contains the vertical deflection
output circuit with a driver for small-aperture (maximum
deflection current 1.8Ap-p) color/B&W TV, monitor/display use and is placed in a SIP13H package. The LA7835
has such features as greatly reduced number of external
parts and low power dissipation. Since both DC feedback
and AC feedback can be provided inside the IC, it is easy
to design the vertical deflection circuit. The LA7835 can
be used in conjunction with single-chip IC LA7650 (NTSC),
LA7680 series (PAL/NTSC) (VIF, SIF, video, chroma, and
deflection circuit) to provide all the functions required for
color TV signal processing.
Features
• Low power dissipation because of on-chip pump-up circuit.
• On-chip 50/60Hz vertical size control circuit.
• On-chip ramp generator.
• On-chip driver circuit.
• Vertical output circuit.
• On-chip thermal protection circuit.
• Minimum number of parts required.
