ABSTRACT:
The dynamic range of a charging current in an open-loop LED driver circuit is scaled to provide a charging current within tolerance for the open-loop LED driver. The scaling of the dynamic range of the charging current is performed transparently to the user, such that user selected parameters for the open-loop LED driver remain unchanged during circuit performance.
