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.
