I am planning on using a Max641 step-up converter. However as a
beginner, I am finding it difficult to choose the external components
- have studied Maxim's data sheet, but still a bit confused about what
Mosfet, inductor and capacitors to go for.
Can anyone make any suggestions. The 5V output will be 1A maximum
current and as well as the rest of the circuit, needs to power a PIC
mcu (does that mean I need to be concerned with the
smoothness/ripple)?
If you need any more information about the requirements, please ask.
As I said, I am a beginner and that includes soldering skills, so
preferable parts that are not too miniature (surface mount is OK but I
have trouble with the really tiny ones). And I would hope to be able
to use parts that are readily available from RS or Farnell in Europe.
Thanks in advance for any help.
p.s. Alternatively if anyone has an alternative suggestion than the
Max641, I would be interested to hear - it will use 2xNiMH 1.2V AA
equivalent batteries, and as I said above, should provide 5V, 1A
output. With minimum external part count, not too miniature and as
efficient as possible.
