DESCRIPTION
Designed for monitors and high performance TVs,
the STV9378F vertical deflection booster can handle flyback voltage up to 90V. More than 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 STV9378F operates with supplies up to 42V
and provides up to 2App output current to drive the
yoke.
The STV9378Fis offered in HEPTAWATT package.
