Hi all,

I'm thinking about switching chips, which would mean going to a 3.3V
micro. The project is a medium sized LED dimmer (4A capacity at 24V).
I made a smaller dimmer using a logic level MOSFET that worked well,
and a larger one that I used a gate driver on.

It would be ideal for this project to not use a driver as I've got to
make a bunch of these, and the costs would add up.

But...I am not familiar enough with MOSFET design to know if I can
successfully drive them directly at 3.3V. Or if by doing that I will
get excessive internal losses.

Any thoughts or parts selection ideas? I used the TrenchFET line on my
last project and it seemed pretty decent.

A common mistake that people make when trying to design something
completely foolproof is to underestimate the ingenuity of complete
fools.
