DESCRIPTION
Designed for monitors and high performance TVs,
the STV9379F vertical def lection boos ter c an 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 2.0A
the yoke.
The STV9379F is offered in HEPTAWATT package.
