we need to make a 33V/1.5A(50w )led driver. I tried using LNK409 but pixl sheet shows warning as IFB IS MORE THAN 220uA! Can you suggest a solution. Is LNK410/420 IS AVAILABLE in market? We searched in Digikey, Mouser and PI distributors in India. But it is not available. Please advice how to get LNK410 in INDIA.
