Hello to all..!!!

I'm looking for a single output , 5V @ 1A, DC-DC step down converter
for an analog application. Does anyone know where can I find one
module like this ?

Thanks,

Hideo.

I'll just rattle off some ideas...
Ebay
Numerous electronics distributors
Thrift Store..maybe for $5.00
Phihong
Omron
Xantrex
Computer power supply...about $50.00CAD...from numerous computer
shops...old or new.. Don't use your own computer supply.. You might
not be able to post more interesting posts. :)

But if you need very clean output...then that I don't know..

Without knowing more about how you would use this power supply,

I can only suggest google.

What input?
What load? Not just analog; a really quiet requirement might have a
switcher feeding a low noise linear device, but for general use a
straight switcher will probably be fine.

So be specific about the application and we might be able to help.

Check Digikey. For really noise-critical apps I can only tell you from
experience that I always rolled my own. And beware of "vaporware" PWM
controllers that look almost too good to be true on the datasheet and
then turn out to be non-stock everywhere.
