Hi,
the slight difference I was refferring to was what
was listed on the web page and what I could actually
get from Digikey. I assumed it would be inefficent,
but as it was charging with the right current I wasn't
too concerned until it started heating up.
I would appreciate it, if someone could explain how
to calculate a proper value for the inductor for
my circuit.
