The LA78040N 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 LA78040N provides a maximum deflection current of 1.7 A p-p, and thus is optimal for small to medium diameter CRTs.
Low power operation achieved by using integrated charge pump circuit
Vertical output circuit
Thermal protection circuit
Excellent crossover characteristics
Supports DC coupling

The LA78041 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 LA78041 provides a maximum deflection current of 2.2 A p-p, and thus is optimal for large diameter CRTs.
