Power the board on and gently feel the top surface of the IN518. If it becomes instantly hot to the touch within seconds, it is either internally damaged or driving a heavy short-circuit downstream. 5. Replacement and Repair Tips
The center pad of the QFN-40 package is a large ground pad used for thermal dissipation and electrical grounding. Proper soldering of this pad is critical for the chip to function correctly and avoid overheating.
Variants include T01, T02, T03, and NT02, which represent specific hardware revisions or performance improvements. Troubleshooting Insights Short Circuit Faults: inx in518 ic pinout diagram top

Pins used to set and monitor the output voltage. NC: No internal connection. Technical Resources
When looking at the IC from the , the pin numbering starts at the circular indentation (pin 1) and proceeds counter-clockwise around the chip. While official datasheets from the manufacturer are difficult to source, repair community diagrams and technical notes highlight several critical voltage pins: Replacement and Repair Tips The center pad of
These precise voltages are critical for the proper operation of the T-Con board and the LCD panel itself.

When looking at the IN518 IC from the (facing the package markings with the pin orientation notch or dot pointing upward/to the left), the pin arrangement follows a standard numbering system. The IN518 is most commonly housed in compact, surface-mount packages like the SOT-23-5 or SOP-8 .
: Common markings include versions such as T01, T02, T03, I01, I02, and NT03. Pinout Configuration (Top View)
The INX IN518 typically comes in a (Quad Flat No-leads) package, which features 40 pins distributed along its four sides. In the industry, it is also frequently referred to as the 1N518 or IN518 . Pinout Configuration (Top View) inx in518 ic pinout diagram top
Feedback/Compensation. This pin receives the feedback signal from the optocoupler to regulate the output voltage.
