Vertical Output IC

LA7846N

Overview

The LA7846N is a vertical deflection output IC for high-definition TV and CRT displays in systems that use a bus control system signal-processing IC. This IC can directly drive (including the DC component) the deflection yoke from the sawtooth wave output from the bus control system signal-processing IC. The color TV vertical deflection system adjustment function can be controlled from the bus system when this IC is used in conjunction with a Sanyo LA768X or LA769XX series TV bus control system signal- processing IC.

The LA7846N provides a maximum deflection current of 3.0 A p-p, and thus is optimal for large diameter CRTs, and can drive the CRTs used in TV sets in the 33 to 37 inch range.

Functions

Low power operation achieved by using integrated charge pump circuit

Vertical output circuit

Vertical Output IC

LA78040

Overview

The LA78040 is a vertical deflection output IC for high-definition TV and CRT displays in systems that use a bus control system signal-processing IC. This IC can directly drive (including the DC component) the deflection yoke from the sawtooth wave output from the bus control system signal-processing IC. The color TV vertical deflection system adjustment function can be controlled from the bus system when this IC is used in conjunction with a SANYO LA768X or LA769XX series TV bus control system signal- processing IC.

The LA78040 provides a maximum deflection current of 1.8 A p-p, and thus is optimal for small to medium diameter CRTs.
