TYPICAL APPLICATIONS
Figures 9 and 10 show ballast schematics, both non-
dimming and dimming. These are power-factor corrected
60W ballasts designed to operate two series connected
F32T8 fluorescent lamps. Both Schematics, Figures 9 and
10, are of previously published ML4831 circuits that have
ML4832
been modified for ML4832 compatibility. The value
changes and component additions made for ML4832
compatibility were for different amplifier compensation,
bootstrap/bias and protection and do not effect the validity
of the circuit description, operational information or
equations.
