Derive Simple High-Current Source from Lab Supply
Abstract:Comprising a standard Force-Sense lab power supply, an additional power supply for the ICs, and a separate control
voltage, this adjustable current source provides a 1-to-1 ratio of control voltage to load current (1A/V).
A similar version of this article appeared in the October 16, 2008 issue of EDN magazine.
When electronic testing requires an adjustable current source, you must often build that piece of test equipment in the lab. You can
easily make such a current……
