frequency
- Internal maximum current limitation.
- Soft start
• Compared with the KB2511B, KB2512 HAS:
- Corner correction

The KB2512 is a monolithic integrated circuit assembled in 32 pins shrunk dual in line plastic package. This IC KB2512 controls all the functions related to the horizontal and vertical deflection in multi modes or multifrequency computer display monitors.

The internal sync processor, combined with the very powerful geometry correction block make the KB2512 suitable for very high performance monitors with very few external components. The horizontal jitter level is very low. It is particularly well suited for high-end 17" and 19" monitors.
