DESCRIPTION
Designed for monitors and high performance TVs,
the TDA8177F vertical deflection booster can han-
dle flyback voltages of up to 70V. In addition, it is
possible to have a flyback voltage which is more
than the double that of the supply (Pin 2). This al-
lows decreasing power consumption or decreas-
ing the flyback time for a given supply voltage.
The TDA8177F operates with supplies of up to
35V and outputs up to 3A_PP to drive the yoke. The
TDA8177F is offered in HEPTAWATT package.
