LNK419EG with 12W output

2 posts / 0 new



can I use LinkSwitch PH419 device for 10V 1,2A output..Because my design is doesn't work...I made design with PIX Expert 9 ...My transformer parameters are great, Leakage inductance is around 1%. But I cannot start circuit.. I did not use OVP circuit and I am trying use CV electronic load to test it..

Except problem with auto restart mode, my Transil clamper is heating up..mine circuit is in the attachment so the pixls file


What do I should do? 


Thank you for answer..

Check your schematic, one leg of D7 should not be connected to ground,.
