Dave,
well the schematic is the same as in the LT specification.
My PCB is a prototype, and I would not like to publish it, because it
contains several bugs.
One one those bugs led to the first change of the initial LT
specification, i.e. I discovered the parasitic diode in parallel to the
heater, by reversing the polarity.
I did not put any taobao.. link anyywhere, so I don't know what you
mean, sorry.
Frank
Frank,
Is there a drawing or scan for the PCB for this circuit? Are the boards or
completed assemblies available for purchase?
The links to the taobao.com site in the blog are obviously dead; they lead
to a department store type retail site.
