I'm currently working on at 22w mains dimming led driver using a diodes inc device
It currently uses a EFD15 gapped core inductor but i'm not sure if i'm pushing my luck on the power rating .
I've built 3 so far without any issue but is it possible to use 2 x efd15 inductors to increase power rating
i can't simply use a bigger core due to height limitations. what advise can you give me on this :confused:
