DESCRIPTION  
.
.
The TDA9109/SN is a monolithic integrated circuit  
assembledin 32-pinshrink dual in line plastic pack-  
age. This IC controlsall the functionsrelated to the  
horizontal and vertical deflection in multimode or  
multi-frequencycomputer displaymonitors.

Theinternalsyncprocessor,combinedwiththevery  
powerful geometry correction block make the  
TDA9109/SN suitable for very high performance  
monitors, using very few external components.  
- INTERNAL PWM GENERATOR FOR B+  
CURRENT MODE STEP-UP CONVERTER  
- SOFT START  
- I2C ADJUSTABLEB+ REFERENCE VOLTAGE  
- OUTPUT PULSES SYNCHRONIZED ON  
HORIZONTAL FREQUENCY  
The horizontaljitter levelisverylow. It is particularly  
well suited for high-end 15” and 17” monitors.  
Combined with the ST7275 Microcontroller fam-  
ily, TDA9206 (Video preamplifier) and STV942x  
(On-Screen Display controller) the TDA9109/SN  
allows fully I2C bus controlled computer display  
monitors to be built with a reduced number of  
external components.
