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, single-

ended output amplifier with a flyback generator. This archi-

tecture minimizes the power dissipation during forward scan-

ning without slowing down the flyback.

The LMV8172 is packaged in a 7-pin TO-220 power pack-

age.
