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
