| TDA8179FS TV VERTICAL DEFLECTION BOOSTER . . . POWER AMPLIFIER FLYBACK SUPPLY VOLTAGE SEPARATED THERMAL PROTECTION DESCRIPTION Designed for monitors and high performance TVs, the TDA8179FS vertical deflection booster is able to work with a flyback voltage more than the double of VS. The TDA8179FS operates with supplies up to 42V, flyback output up to 92V and provides up to 2App output current to drive to yoke. The TDA8179FS is offered in HEPTAWATT package.
