TDA8177F
VERTICAL DEFLECTION BOOSTER
. . . . . .
POWER AMPLIFIER THERMAL PROTECTION OUTPUT CURRENT UP TO 3.0APP FLYBACK VOLTAGE UP TO 70V (on Pin 5) SUITABLE FOR DC COUPLING APPLICATION EXTERNAL FLYBACK SUPPLY
HEPTAWATT (Plastic Package) ORDER CODE : TDA8177F
DESCRIPTION Designed for monitors and high performance TVs, the TDA8177F vertical deflection booster can handle 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. PIN CONNECTIONS
7 6 5 4 3 2 1 Tab connected to Pin 4
The TDA8177F operates with supplies up to 35V and provides up to 3APP output current to drive the yoke. The TDA8177F is offered in HEPTAWATT package.
