Re: Line Drive™ - 15A Linear Driver
Well, after some struggling with a board that
failed to produce any output (turned out to
be a resistor soldered in the wrong place) I
can now report some success!
The Line Drive Rev. 1.5a is happily pumping
15A into the test load. The dropout is about
500mV, at least within the granularity of the
diode stack. It could be even less. So in
the current test setup, it's disspiating about
7.5W @ 15A.
The thing that surprises the heck out of me
is that the thing acts like it WANTS to do
more. A quick calculation suggests that with
some modifications and enough heatsinking,
outputs in excess of 50A are theoretically
possible under the right conditions.
15A though is enough for now. Next up are
going to be some scope tests. Stay tuned
and hope for the best. :beer:
