Overview

The LA78040N 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 LA78040N to a Sanyo LA768X series or LA769XX

series bus control system signal-processing IC.

Since the LA78040N provides a maximum deflection current of 1.7Ap-p, it is optimal for small and medium size CRTs.

Functions

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

• Vertical output circuit.

• Thermal protection circuit.
