Overview
UTC78045 LINEAR INTEGRATED CIRCUIT TV and CRT Display Vertical Output IC with Bus Control Support DESCRIPTION The UTC78045 is a vertical deflection output for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC.
The sawtooth waveform the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component).
FUNCTIONS * Built-in pump-up circuit for low power dissipation.
* Vertical output circuit.
* Thermal protection circuit.
