Does anyone use or have experience with the LM3671 from TI.
It looks like a sweet little package. I’ve stayed away from bucks in the past cause I’ve always found the inductors to add to much cost and have a large foot print. But this only requires a little 2.2uH inductor. The recommended inductor is this style.
Page 16 of the data sheet says this about the inductor…
“A more conservative and recommended approach is to choose an inductor that has a saturation current rating greater than the maximum current limit of 1150 mA.
A 2.2-µH inductor with a saturation current rating of at least 1150 mA is recommended for most applications. Inductor resistance should be less than 0.3 Ω for good efficiency. Table 1 lists suggested inductors and suppliers. For low-cost applications, an unshielded bobbin inductor could be considered. For noise critical applications, a toroidal or shielded-bobbin inductor should be used. A good practice is to lay out the board with overlapping footprints of both types for design flexibility. This allows substitution of a low-noise shielded inductor, in the event that noise from low-cost bobbin models is unacceptable.”
Can anyone explain why one of these types of inductors wont work?
They’re so much cheaper and smaller. Have a found a little winner, or am I missing something?
Thanks in advance.
