My highest priority criteria for most of the switchers I use are (a) =20 very small footprint and (b) low cost. Next nice-to-have is (c) low =20 part count. I am willing to work around the auto-design thing. I haven't looked into LT for some years, but last I remember they =20 failed miserably at all 3. Lots of required passives, large package =20 sizes (to have all those pins to add the passives), and quite pricey. =20 But they have a rep for being very good quality parts. I'll have to =20 revisit them again. Cheers, -Neil.
