REV. 2
FEATURES SUMMARY POWER AMPLIFIER THERMAL PROTECTION OUTPUT CURRENT UP TO 2.6APP FLYBACK VOLTAGE UP TO 90V (on Pin 5) SUITABLE FOR DC COUPLING
APPLICATION EXTERNAL FLYBACK SUPPLY
DESCRIPTIONDesigned for monitors and high performance TVs,
the STV9379FA vertical deflection booster can
handle flyback voltage up to 90V. Further to this, it
is possible to have a flyback voltage which is more
than the double of the supply (Pin 2). This allows
to decrease the power consumption, or to de-
crease the flyback time for a given supply voltage.
The STV9379FA operates with supplies up to 42V
and provides up to 2.6APP output current to drive
the yoke.
The STV9379FA is offered in HEPTAWATT pack-
age.
