PULSE DRIVEN VERTICAL BOOSTER - . . ADVANCE DATA OUTPUT CURRENT UP TO 2.5App 70V MAXIMUM FLYBACK VOLTAGE INTERNAL FLYBACK GENERATOR INTERNAL REFERENCE VOLTAGE GENERATOR INTERNAL RAMP GENERATOR SAWTOOTH STARTED BY THE END OF SYNC PULSE OR BY AN INTERNAL MONOSTABLE THERMAL PROTECTION CLIPWATT 11 (Plastic Package) ORDER CODE : STV9303W DESCRIPTION The STV9303 is a pulse driven vertical booster intended for use in color TV. It includes a vertical ramp generator specially designed to fit with deflection processors like STV2102 or STV2110 which provide a 10.5 line lengh vertical pulse. The discharging of the sawtooth capacitor is triggerred by the trailing edge of the vertical sync and the charging by the leading edge. During the sync pulse duration, the sawtooth will remains at its bottom value. Another possibility is to use the internal monostable (by connecting an external capacitor on Pin 5) to define the point where the sawtooth will restart. This second possibility is very usefull to avoid interlacing problems when using a conventional deflection processor delivering a small duration vertical pulse. The STV9303 includes a very efficient power amplifier for direct driving of a TV picture tube in B & W or color television. For power consumption saving, a flyback generator is also included. The current and voltage capabilities (2.5App max output current and 70V flyback peak voltage), make this IC also suitable for large screen TV sets. Thermal protection is also provided.
