LA78041

Overview

The LA78041 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 LA78041 to a our company LA768X series or

LA769XX series bus control system signal-processing IC.

Since the LA78041 provides a maximum deflection current of 2.2Ap-p, it is optimal for large size CRTs.

Functions

• Low power operation achieved by using integrated charge pump circuit.

• Vertical output circuit.

• Thermal protection circuit.

• Excellent crossover characteristics.

• Supports DC coupling.
