Re: DC-DC converters

Your link was cut off - try using "tinyurl.com" to give us something to look

I haven't seen a design touted as a Cuk converter outside of textbook pages;
the idea is great for reducing ripple: input, otuput, or both.

Are you in need of general learning? A single device? A design-your-own
1k/mo production solution? Is your need non-isolated?

What are the pros and cons of the various DC-DC step-up converter
designs (say, 12V to 18V, 50 watts total)?

I could use one for my old laptop (366 mhz, it wants 18V @ 2.7A).

I went to this website:
http://www.powerdesigners.com/InfoWeb/design_center/articles/DC-DC/co...


and I see there are CUK converters, Boost, Buck Boost, etc.

My intuition tells me there are trade-offs in efficiency, ease of
construction, cost, consistency and durability between each of these
methods.

Any suggestions guys?
