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.

The TDA8177F operates with supplies up to 35V and

The TDA8177F is offered in HEPTAWATT package.
