LNK306 (LNK305) in galvanically isolated LED driver

3 posts / 0 new

Hi! Would you help me with circuit of depictured item? "LNK306" or "LNK305" may be red easily, inspite of resolution's lack. Transformer is obvious too - so the driver is galvanically separated. What do you think of it?

Sorry it was my fault - not "LNK406" but "LNK305" or "LNK306".


I am not sure if the IC is LNK305 or LNK306 due to lack of image resolution. However, the driver is not isolated since the IC is intended for non-isolated application. There is even no safety isolation on the transformer that might suggest isolated driver.
