The minimum operating frequency must
be lower than f 100% of f IGN (whichever is
lower). R FMIN also programs I MIN and I IPH ,
so R FMIN must be set first.
R CS sets the maximum ignition current
Select R FMIN
Use Graph 1 or Graph 2

preheat mode. R IPH must be set after
R FMIN .
During preheat, an internal 1.3 μ A
current source at pin CPH charges
external capacitor CCPH. Preheat

R MIN sets the lower phase boundary
corresponding to minimum lamp
power when V DIM = 0 volts. R MIN must
be set after R FMIN .
