DESCRIPTION
Designed 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 decrease
the flyback time for a given supply voltage.
The STV9379F A operates with supplies up to 42V
and provides up to 2.6A
the yoke.
The STV9379FA is offered in HEPTAW ATT package.
