Maxim IC frustration - hard to find components

[[email protected]]

I don't know why Maxim makes it so difficult for small companies to
design with their components.
I am developing a new consumer electronics product. Unfortunately, I
planned to use 4 Maxim chips that are hard to find in small quantities
(1-40). Standard distributors like Arrow, Mouser and Digikey don't cary
them. These components are excellent matches for my design needs. Maxim
offers some of their ICs for purchasing on their website, but not the
ones listed below. Perhaps someone can recommend a broker or exchange
website where rare Maxim components can be purchased at reasonable
prices. I would love to find alternatives to these components if
someone can offer some advice. National, Linear and Analog devices
simply cant match the selection, sophistication and price of switching
regulators and battery charging ICs. Please feel free to recommend
other IC manuafacturers that specialize in these types of components.

DS2745 Low Cost I2C Battery Monitor
(chosen for its ability to cumulatively measure voltage & current to
estimate battery life, + its low cost, $1@1K)
http://www.maxim-ic.com/quick_view2.cfm/qv_pk/4994

MAX1555 Dual-Input, USB/AC Adapter, 1-Cell Li+ Battery Chargers
(chosen for its ability to intelligently charge a 1-cell lithium from
a wall adapter or USB port 5v rail, low cost .85@1K)
http://www.maxim-ic.com/quick_view2.cfm/qv_pk/4002

MAX1522 Simple SOT23 Boost Controllers
(chosen for its high frequency operation - small inductor, only a few
external components, low cost $1.07@1K)

MAX1724 1.5µA IQ, Step-Up DC-DC Converters in Thin SOT23-5
(chosen for its ultra low quiescent current, only needs a 10uh
inductor, has built in FET, very few external components, low cost
$1.45 @ 1K)

Yoiu're getting more irritating than those you seek to castigate. More than
75% of the replies I see from you betray the existance of stuff (spam,
crossposts, FUD) I wouldn't know about because my ISP server has decent
filtering. Please, get a hobby other than pointless spam amplification.

Have you checked out their websites (not just the Digi-Key listing)? I
don't know about National and Analog, but I can tell you with assurance
that Linear Technology has many DC/DC converters (buck, boost and
buck-boost, as well as chargers) for battery powered applications that
not only match but surpass the performance of Maxim parts, in a smaller
package and without the delivery headaches you mention. As for price,
it depends on the part, but you can expect to pay more for better
performance in a smaller package.

For example, to replace the MAX1724, check out the LTC3525. The LTC
part is smaller, uses the same quantity and size of external
components, and has much higher efficiency and better output regulation
(conveniently not shown in the Maxim performance curves), while the
output ripple is significantly lower. The LTC part also offers more
sophisticated features such as output disconnect and the ability to
regulate Vout even when Vin>Vout (a neat trick for a boost converter).
Some other cool parts are the LTC3531 and the LTC3526, just to give two
more examples. For buck converters and chargers (both linear and
switching), the list of LTC parts you can choose from is so long I
wouldn't know where to start. In my opinion, Maxim hasn't really come
out with anything new in this arena for some time. (And - in case
you're wondering - I'm not an LTC Marketing guy!)

What are your input, output, and load requirements?

Happy hunting,
Dave
