LA78041
12,10 EGP
LA78041 provides a complete vertical output solution for high-definition CRT displays and television monitors. This monolithic integrated circuit handles the entire vertical deflection process within a single TO-220-7H package. Consequently, repair technicians rely on this chip to fix “single horizontal line” screen failures and vertical distortion.
High-Performance Output Stages
The LA78041 features a built-in pump-up circuit that reduces internal power dissipation. Specifically, this design allows the IC to drive large-sized deflection yokes with high efficiency. Additionally, the chip includes a thermal shutdown circuit. Furthermore, this internal protection prevents the device from burning out during extreme operating conditions. Consequently, the LA78041 maintains stable screen geometry even after hours of continuous operation.
Industrial Grade Reliability
Moreover, this IC supports a wide range of supply voltages. It handles up to 34V for the output stage, which suits various chassis designs from major manufacturers. Specifically, it offers a peak output current of 2.2A. Furthermore, the low crossover distortion ensures a smooth vertical sweep across the entire screen surface. Additionally, the compact 7-pin layout simplifies the soldering process during board-level repairs.
