Function: Color TV Vertical Deflection Output Circuit
X0640C = LA7830 ( Sanyo )
The LA7830 is a monolithic linear IC designed for small-aperture color TV vertical deflection output and has such features as greatly reduced number of external parts and low power dissipation. The LA7830 can be used in conjunction with the LA7620 series for video chromadeflection use and the ~~7800 series for deflection use and the LA7850 series for display use to form a stable and compact vertical output deflection circuit.
Function: TV and CRT Display Vertical Output IC with Bus Control Support
Package: TO-220-7H Type
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.
