power question

2003-12-23 by David Willmore

Hello, all.

All of the power usage comments I've seem never mention
which supply the current draw is for.  This got me
thinking what kind of power supply curcuits everyone
is using.  That lead to a few questions:

What is the current draw at max/sleep for each (3.3 and
1.8V) supply?

Does anyone know of a simple chip that does two channels
of buck mode switching step down?

Is anyone using anything but linear regulation?

I don't remember seeing them, but there have to be power
supply sequencing requirements.  Does anyone know what
they are?  (page numbers in the manual where I failed to
read them)

Happy holidays!

Cheers,
David
