TDA8177F
VERTICAL DEFLECTION BOOSTER
FEATURES SUMMARY POWER AMPLIFIER

Figure 1. Package
THERMAL PROTECTION OUTPUT CURRENT UP TO 3.0APP FLYBACK VOLTAGE UP TO 70V (on Pin 5) SUITABLE FOR DC COUPLING PPLICATION EXTERNAL FLYBACK SUPPLY
DESCRIPTION Designed for monitors and high performance TVs, the TDA8177F vertical deflection booster can handle 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 allows decreasing power consumption or decreasing the flyback time for a given supply voltage. The TDA8177F operates with supplies of up to 35V and outputs up to 3APP to drive the yoke. The TDA8177F is offered in HEPTAWATT package.
