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 triggerr ed 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. Thi s second poss ibility 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 generat or
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.
