Hey guys! I have designed a regulator PCB board for the Wii:
It works great and is actually quite small at just 24.6 x 20.5 mm and I used SOT-23-5 chips so it would be easier to solder than QFN since my attempt at the PowerMii Lite was a failure...
Anyway, back to the point. I'm looking to improve my board.
I have added some charging management ICs but charge and play is not supported.
I want to do something like this:
https://bitbuilt.net/forums/index.php?threads/easy-charge-and-play-circuit.1417/
But on an SMD scale to keep the size small. Unfortunately I'm a bit lost on how this circuit works exactly.
It looks like all I need is an SMD size P-Channel MOSFET, an SMD Schottky diode, an SMD 100K resistor and possibly a small size inductor too. There are just so many options on Digi-Key and I feel lost...
Any idea how I can make this happen?
