While im waiting for parts for my AC-LED project, ive started on the DC-LED project. This involves a tiiiiiny IC:
Data sheet: http://www.national.com/ds/LM/LM3407.pdf (circuit in question here, is the typical application).
NS suggests the use of SMD components - which differ a tiny bit, compared to leaded components. I havent worked much with SMD components before, so my primary concern, is:
The inductor.. It must be 33uH and have a DCR between 100u and 3.3 ohm. Found one that should have a DCR of 0.045 @ 33uH - should be just fine? Im unsure whether i want a high or low value here..
Anything i should be aware of, when using leaded components instead of the suggested SMD's ?
