Inx In518 Ic Pinout Diagram Top May 2026

(also referred to as ) is a high-performance DC-to-DC converter IC specifically designed for use in LCD LED TV T-CON boards . It is typically found in a QFN-40 package (Quad Flat No-leads with 40 pins). Pinout and Functional Diagram

If you need the exact pinout for a specific IN518 variant (e.g., IN518A, IN518B) or a different package (QFN, BGA), please provide the full part marking and package type. inx in518 ic pinout diagram top

(6x6mm approximately) designed for space-constrained T-CON boards. Applications: Primarily used in Innolux (INX) (also referred to as ) is a high-performance

5. Signal Integrity Notes from Top View

• TX pins (9–20): Series 100Ω resistor at pin (reduces overshoot).
• RX pins (21–32): No series resistor – direct to sensor.
• I2C pins (5,6): Pull-ups to VDD33 (2.2kΩ typical).
• Unused TX/RX: Leave floating (not to GND).

Recommendation

Obtain and follow the official INX IN518 datasheet and application notes for exact pin functions, electrical characteristics, package-specific pin numbering, recommended external components, and PCB layout diagrams. Do not rely on the generic mapping above for production.

While a full 40-pin table is often proprietary, technical analysis and live data sheets identify these critical functional pins and zones: Input Power (VCC/VIN): 12V DC input from the main board. AVDD Switching Pin:
