Leo_W Posted August 20, 2020 Share Posted August 20, 2020 Hi Digilent, My Nexys 4 DDR couldn't be powered on and I found that the IC20 on board was disappered. However, I can't find this chip in the schematic. Could you let me know this IC's type and I will buy it to repair board myself. Thanks Link to comment Share on other sites More sharing options...
JColvin Posted August 20, 2020 Share Posted August 20, 2020 Hi @Leo_W, That particular IC is the Analog Devices ADP121 (specifically ADP121-ACBZ33), though looking at the picture you provided, it seems like there is some heat damage around there so I don't know if any anything else on the board is damaged. Thanks, JColvin Link to comment Share on other sites More sharing options...
