Hey, so I'm noticing on a number of my regular projects the only downside to switching to the 3.X teensies has been the 9mA/25mA MAX 3v3 drive potential of the pins. This compares to the 5V 20mA/40mA MAX of most of the arduino AVRs. In the latter case I found I had decent performance characteristics from a large variety of logic level mosfets. In the teensy case I'm nervous about driving the more limited selection of logic level power mosfets at increasing frequencies, because I suspect I'm driving them really poorly and don't have the scope tools (or background E.E knowledge) to figure out how badly I am driving them or what my max frequency can be (i also worry that i flirt the edge of the Vgs min and Vgs max tolerances on the fets). I've tried reading a few application notes and now understand more, to the point that I know I don't understand enough (apparently, it's not entirely as simple as just charging a capacitor)

Long story short, does anyone know how to approach finding a "good" mosfet driver for general teensy applications? I'm hoping to drive some N-mosfets at 30kHz, or even higher if it's possible with a proper driver. That would be above the AVR speeds I was using (which even with the much better 20mA driving current I didn't bother going above 10Khz in most cases.) I also would hope it wasn't smaller than SOT-23 or SC70 with respect to ease of hand soldering SMD components.

I tried so far searching "teensy mosfet driver recommendations"
I tried going through the octoparts common parts library (seems lacking any recommendations)
And I have tried once or twice going through digikey, but have limited confidence in my approach to qualifying the drivers.

So I expect my question might result in either an answer of the category
"Here is an industry standard driver, to mosfet drivers as LM317 is to linear regulators [or something like that]"
"Here are the type of characteristics you look for when filtering digikey/mouser/elsewhere options for mosfet drivers"
"Other categories of response"

Hopefully I've managed to narrow down the scope of the question in a way that is still useful to a lot of people getting started with "powering powerful things with the teensy." I've taken for basics that people understand a little about mosfets, N vs P, etc, and if they don't, I recommend the adafruit tutorials on mosfets they were fun and helpful for me to understand a little bit about g-s-d type principles.
