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 deflec-

tion processors like STV2102 or STV2110 which

provide a 10.5 line lengh vertical pulse. The dis-

charging of the sawtooth capacitor is triggerred by

the trailing edge of the vertical sync and the charg-

ing 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 possi-

bility 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 am-

plifier 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 capabili-

ties (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.
