STV9379FA

STV9379FA VERTICAL DEFLECTION BOOSTER . . . . . . POWER AMPLIFIER THERMAL PROTECTION OUTPUT CURRENT UP TO 2.6APP FLYBACK VOLTAGE UP TO 90V (on Pin 5) SUITABLE FOR DC COUPLING APPLICATION EXTERNAL FLYBACK SUPPLY DESCRIPTION Designed for monitors and high performance TVs, the STV9379FA vertical deflection booster can handle flyback voltage up to 90V. Further to 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 STV9379FA operates with supplies up to 42V and provides up to 2.6APP output current to drive the yoke. The STV9379FA is offered in HEPTAWATT package.
