LA7835 TV Vertical Deflection Driver

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.
