LMV8172
LMV8172 is Vertical Deflection Output Amplifier manufactured by National Semiconductor.
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.
Features n n n n n High output current Flyback generator Minimum external part count Works with single or dual supplies Low cross-over distortion
Applications n Vertical deflection for monitors and TVs
