Hi all,

I'm building a switching power supply with LM2576, and it's datasheet.

Ouput power from trafo, before bridge and so on : 120 VA 2 x 25V

Output power from switch power supply: 2 to 30 V and 3A


As i plan to add and additional filter, i only want to know, if following inductors are a good choice?

Bournes 21045 -H-R-C Toroid 22µH 7A

Murata 3300 Series 33220C 22µH 5,1 A

As usual, thanks a lot for your help.

General I follow the datasheet and it say it will improve then I see no problem doing it and the parts you selected seem legit and should work..Oh almost forgot I would get the highest amp rating cause you will pull more current then the part is rated for and cause alot of issues..I would think it would saturate the coil but I might be wrong here since I am the noob.

 

Thanks a lot for your help.
