Many of the design issues described above have also been overcome in the ballast
circuit of reference design IRPLCFL4. The design, however, required two additional
operational amplifiers and additional circuitry since it is based on the IR2156 control IC,
which does not incorporate the necessary dimming circuitry. This circuit therefore has a
relatively high component count.
