Inx In518 Ic Pinout Diagram Top !new! Site

Due to the narrow trace pitches typical of QFN architectures, the INX IN518 is subjected to extreme thermal and electrical stress. The SW-to-GND Short Circuit Phenomenon

When substituting, always check the and Current rating . As long as the replacement diode has equal or higher ratings and fits the through-hole spacing (standard 0.1" to 0.3" spacing), the pinout remains identical (Band = Cathode).

: Verify the chip version marking (e.g., IN518-T03 ) against the exact chip being replaced to confirm component package size matches up perfectly with the footprint (e.g., a 4mm x 4mm footprint with a 0.5mm pitch).

For further procurement, you can find the IN518 IC through global distributors such as AliExpress, Worldway Electronics , and IndiaMART . Due to the narrow trace pitches typical of

Since the INX IN518 is commonly associated with (often found in TFT panels), this pinout reflects the typical 40-pin TSSOP or QFP top-view configuration. If your specific IN518 variant differs (e.g., audio amplifier or power IC), please verify with the exact datasheet.

The IN518 is housed in a QFN-40 package with a center pad used for grounding and thermal dissipation. The pins are arranged around the four sides of the chip. The table below outlines the documented and inferred pin functions based on real-world schematic analysis and repair logs. Switch node output for driving power circuits

Below is the pin mapping (pins numbered counter-clockwise from index mark on top left).
