LA7845
Vertical Deflection Output Circuit
Overview
The LA7845 is a vertical deflection output IC for high-
resolution television and CRT display systems that use a
bus controller system signal processing IC. It can directly
drive the deflection yoke (including the required DC
component) from the bus controller system signal
processing IC's sawtooth waveform output. Connecting
the LA7845 and a Sanyo TV bus control system signal
processing IC in the LA7615 series allows all functions of
a color television signal system to be processed by the bus
system. Since the LA7845 has a maximum deflection
current of 2.2 Ap-p, it is optimal for use in large aperture
products, and is capable of driving 33 to 37 inch class
monitors.
Features
• Low power dissipation due to the provision of a built-in
pump circuit
• Vertical output circuit
• On-chip thermal protection circuit
• Good crossover characteristics
• Supports DC coupling
