I'm looking for a switching regulator chip. Something inexpensive like
the MC34063, but not limited to 100 KHz because I need to reduce the
physical size of my layout, especially the inductor. Not having to use a
current sense resistor would be nice too.

The basic operating parameters will be 8V in, 3.3V out, at 1 amp.

I don't have prices but the Micrel range of switching chips might be worth=

looking at.

The MIC4576  can pump out 3A   runs at 200kHz, same pinout as LM2576 and is=

available in fixed 3v3 or adjustable 1v23 - 33v versions, input is 4 -36v.

For 1MHz and 2MHz there are the MIC2204,2202 (max 5v5 in though) or many=20
other variants with 4v5 - 26v in @ 600kHz - www.micrel.com
