LMV8172 Vertical Deflection Output Amplifier May 1997 LMV8172 Vertical Deflection Output Amplifier General Description The LMV8172 is a monolithic amplifier for driving the vertical deflection yoke of a CRT. The IC is a differential input, singleended output amplifier with a flyback generator. This architecture minimizes the power dissipation during forward scanning without slowing down the flyback. The LMV8172 is packaged in a 7-pin TO-220 power package.
