Hi guys, I started this thread because my PC's PSU stopped working. When I opened it to check what the problem is, I found two elements damaged, they are a Power Mosfet (CEF02N7) and a resistor of 1.2Ohms/1W. Additionaly connected to mosfet gate there are a small IC, on something like a SOT23-6 package, whose code marking is EA546 or EAS46, the problem is that after hours searching Internet I can NOT find what is this IC and a datasheet of it. Is almost sure that this IC is also damaged because it was connected between gate and source of mosfet and this last is damaged (when i measure between gate and source it shows a resistante of 80 ohms aprox in both directions, ohh so bad.). Please if anyone knowns what is this IC I would appreciate some help. Thanks in advance, also to my friend who let me wrote this. Yosmany325.
