Not seeing any such footnote. I've gotten used to the features having=20
the best case situations listed and qualifications later in the detailed=20
specs, but a footnote like that would significantly contradict the=20
"Delivers up to 5 A continuous 6 A peak current" feature listed.=20
"continuous" being the key word here.

Actually, I see these specs:
Output current (cont.) IOUT1, 2 =3D =96 5A Min, 5 A Max.
Output current (peak) IOUT1, 2 =3D =96 6A Min, 6 A Max, where tp < 100 ms; =
T=20
=3D 1 s

Either way, looks like I have to choose something better.

Cheers,
-Neil.
