LA78045 - LA78045 Ordering number : EN7881A
Monolithic Linear IC
TV and CRT Display Vertical Output IC with Bus Control Support
The LA78045 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 LA78045 to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC.
• Built-in pump-up circuit for low power dissipation. • Vertical output circuit. • Thermal protection circuit.
