8 / 12 page ![]() 8 www.irf.com 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: 2 2 2 % 2 4 % 2 2 % 4 % 2 2 % % 4 1 4 32 1 32 1 2 1 C L V V V C P LC V C P LC f DC − − − + − = π π (8) ] 4 2 ) 2 2 [( tan 180 3 % 3 2 % 2 % % 2 % % % 2 % 1 % f LC P V f L V P C P V π π π ϕ − − = − (9) 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: This ballast design procedure has been sum- marized into the following 3 steps: Figure 3, Simplified Ballast Design Procedure 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.
