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
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.
HEPTAWATT
(Plastic Package)
ORDER CODE : TDA8177F
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.
