LNK302DN LinkSwitch-TN Power Supply IC - SO-8C, 700V MOSFET

LNK302DN power supply controller IC for repairing compatible switching power supplies and electronic equipment. This LinkSwitch-TN series component integrates a power supply controller and 700V MOSFET in a compact SO-8C surface-mount package. Product details • Part number: LNK302DN • Series: LinkSwitch-TN • Package: SO-8C surface mount • Type: Off-line switching power supply IC • Integrated MOSFET rating: 700V • Quantity: 1 chip Match the part number and package to your original component before ordering. Installation requires surface-mount soldering skills. JBL EON 515XT Power Supply Repair Example: We successfully repaired a JBL EON 515XT powered speaker with a no-power fault by replacing the LNK302DN at U608. During troubleshooting, the removed chip measured approximately 5.9Ω between pins 1 and 8, while the corresponding board pads measured open circuit after removal, helping isolate an internal short. Replacing the chip restored operation. The FAN7380 gate driver at U603 is another component to investigate when diagnosing similar JBL EON 515XT power supply faults, although the LNK302DN was the confirmed failed component in our repair.
