Overview
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.
Functions
• Built-in pump-up circuit for low power dissipation.
• Vertical output circuit.
• Thermal protection circuit.
