DESCRIPTION
Designed for monitors and high performance TVs,
the TDA8177F vertical deflection booster can han-
dle flyback voltage up to 70V. 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.
