LNK302 dummy load ?
포럼: AC-DC Conversion Forum
Hi, We want to do a 5V, 100mA circuit from 100-265VAC with LNK302. The datasheet says a dummy load is required if an opto isnt used...it shows 3k3 being used when vout = 12V.....so , thats 44mW....so presumably, if we make output = 5v , then a 560R dummy load
