LA78040B The Vertical Deflection Output IC With Bus Control Support for TVs and CRT Display TO-220-7

The LA78040B is a vertical deflection output IC for TVs and CRT displays with excellent image quality that use a BUS control system signal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the saw tooth wave output from the BUS control system signal processing IC.

Features :

Low Power Dissipation: Equipped with a built-in pump-up circuit that minimizes power consumption, making it energy-efficient.
Integrated Vertical Output Circuit: Simplifies design by incorporating essential vertical deflection components into a single IC.
Built-in Thermal Protection Circuit: Ensures safe operation by protecting the IC from overheating, enhancing longevity and reliability.
Excellent Crossover Characteristics: Provides smooth transitions and reduces distortion, contributing to high-quality image reproduction.

Specifications :

Note: Current flowing into the IC is positive (+) and current flowing out is negative (-).
