POWER AMPLIFIER
THERMAL PROTECTION
OUTPUT CURRENT UP TO 2.0APP
FLYBACK VOLTAGE UP TO 90V (on Pin 5)
SUITABLE FOR DC COUPLING APPLICATION
EXTERNAL FLYBACK SUPPLY
DESCRIPTION
Designed for monitors and high performance TVs,
the STV9379F 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 decrease
the flyback time for a given supply voltage.
The STV9379F operates with supplies up to 42V
and provides up to 2.0APP output current to drive
the yoke.
The STV9379F is offered in HEPTAWATT package.
