Win, Are there any P-channel Power MOSFETS that will work at 3.3V
supplies, 300mA < ID < 1A ??

Thanks!

I'm not Win, but here's a couple:

est, avail at Digikey.

There's plenty more if you allow Id > 1A, but I suppose you
want low gate charge.

Very nice, Spef...!

FDG314P 25V 63pF 1.5-ohms at Vgs = 2.7V
NDS332P 20V 195 0.41

It's interesting how the related n-channel devices fare much
better for low gate charge, for similar R(on).

Now can either of you two recommend a companion Schottky (max reverse
voltage is 4V)?
