Hi Guys,
Im currently designing switching power suplly using L5973D. I abit consfused in the LC selection for the LC filter. I have fixed the value of L to 22uH, while c 100uF. I have notice the emmision at ouput decrease as output C value is tuned up to 150uF to 330uF. Hw do we determine wht would be suitable value of cap to be used? the range of cap permited on IC spec is form 100uf to 440uF. Pls advice...
Appriciate your points...
