Universal Input Constant Average Currrent LED Lamp Power Supply
This circuit provides a constant average current output, which may
be used to power LED lamps. The circuit maintains a constant
average current and the value of C4 capacitor controls the peak-to-
peak ripple, which decreases with increasing capacitor value. If
very high current ripple values are permissible then C4 may be
omitted. The following BOM provides a list of suggested
components.
