The LA7875N, LA7876N are designed for use in internet TVs and high-resolution CRT monitors that require a narrow vertical return period. These ICs succeed in achieving a narrow vertical return period by adopting a new 3x pump-up technique in the voltage pump-up circuit. Since this allows the use of a reference voltage lower than that used with the 2x pump-up technique, the LA7875N, LA7876N achieve a significant reduction in power dissipation. Also, since the bus control system signalprocessing IC can control these ICs and these ICs can directly drive the deflection yoke for all frequencies down to DC from the sawtooth wave output, shift operation, which is required for wide aspect ratio television, can be controlled from the bus. Since the LA7875N has a maximum deflection output current of 2.2 A p-p, it is appropriate for use in medium-size CRTs. Since the LA7876N has a maximum deflection output current of 3 A p-p, it is appropriate for use in larger CRTs.
