REFERENCE DESIGNS
Two typical LED driving applications are shown.
Firstly a maximum brightness solution and
secondly an optimised battery life solution.
Maximum brightness solution
This circuit provides a constant current output to
the LED by rectifying the switching pulses. This
ensures maximum LED brightness.
