IR2159 Programmable Inputs
In order to program the MIN and MAX settings
of the dimming interface, the phase of the out-
put stage current at minimum and maximum
lamp power must be calculated. This is obtained
using the following equations:
This ballast design procedure has been sum-
marized into the following 3 steps:

With the lamp requirements defined, the L and
C of the ballast output stage selected, and the
minimum and maximum phase calculated, the
component values for setting the programmable
inputs of the IR21592 are obtained with the fol-
lowing equations:
Ballast Designer Software
Included with the design kit is the Ballast Designer
Software which allows for selection of different
lamp types, different input voltage ranges or dif-
ferent lamp configurations. The software then
performes all of the necessary design iterations
and generates new schematics and a bill of ma-
terials.
