I'm looking for an LED Driver with an Ultra Wide Range input.
Input Range: 18....265V AC and/or DC
Output: 4..5W (no dimming no PFC...)
Topology: Buck (possible to use LYT0006?)
I found the Design Idea DI-152 which looks very similiar what I need but in flyback toplogy. Is it possible to use Buck topology? How can the "Floating Constant Current Source" used in Buck toplogy?
