Description :

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.
