TDA8177F
VERTICAL DEFLECTION BOOSTER
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.
