Convergence Waveform Generator
IC for Projection TV
The MC44615A is a bipolar integrated circuit designed to be used with the
control circuitry for projection television convergence systems. The function of
the integrated circuit is to generate the required voltage waveforms that will be
applied to the convergence control circuitry. This control circuitry will apply them
in the proper amplitude and combination for use in driving the convergence coils.
