Vertical Output IC Vertical Output IC
The LA7841 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 LA7841 provides a maximum deflection current of 2.2 A p-p, and thus is optimal for large diameter CRTs.
Low power operation achieved by using integrated charge pump circuit
Vertical output circuit
Thermal protection circuit
Excellent crossover characteristics
Supports DC coupling
