Description :

The LA78040 is a vertical deflection output IC for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component). Color TV vertical deflection system adjustment functions can be controlled over a bus system by connecting the LA78040 to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC. Since the LA78040 provides a maximum deflection current of 1.8Ap-p, it is optimal for small and medium size CRTs.


1. Built-in pump-up circuit for low power dissipation.
