Hi Andy
The picoverter needs 15V for the IR2184 FET drivers.
This permits driving a power board's FETs directly from the IR2184
If using a totem pole driver type power board then
the 15V is not needed, it can be only 12V and this output will
be sent to the transistors of the totem pole drive.
I have not tested the picoverter with 12V supply for the IR2184
but I expect it will work with totem pole type power boards.
Whichever supply you choose, keep in mind how much current will be needed
when you include any fans that are to be driven from the supply.
When only running the picoverter or nanoverter, only about 50mA is needed
at 15V. Adding a fan could mean needing 0.7 Amps more, and larger fans
will likely need some care in the 15V supply choice, even going to separate
supplies for the fans.
