Complete Guide: INX IN518 IC Pinout Diagram and Datasheet
Are you working on a legacy electronics project or repairing an industrial control board? If you’ve come across the INX IN518 IC, you might be searching for reliable pinout data. Since this component is often associated with specialized or legacy industrial hardware, finding the right diagram is crucial for correct implementation.
The INX IN518 (also identified as IN518 or 1N518) is a specialized Power Management Integrated Circuit (PMIC) and DC-to-DC converter primarily used in Innolux LCD display modules. It typically comes in a compact QFN-40 (Quad Flat No-leads) package, designed for space-constrained electronics like high-performance LCD panels and wearable devices. Pinout and Key Technical Features
Connection List:
While specific manufacturer datasheets are often proprietary to Innolux, technical reference guides and community-shared diagrams reveal critical pin functions: Package: QFN-40 (40-pin layout). Voltage Channels: VGH (Voltage Gate High): Typically around 27V. VGL (Voltage Gate Low): Negative voltage rail. AVDD: Analog supply voltage, often around 17V. Logic Supply: Standard 3.3V and 12V rails. Key Pins: Pin 4: Often used as the 12V input. Enable Pin: Controls the IC's operational state.
If the IC becomes excessively hot immediately after power-up, it usually indicates an internal short or a short in the display panel's COF (Chip-on-Film).
How to Read and Use the Inx In518 Ic Pinout Diagram Correctly
Step-by-Step for Circuit Design
- Power supply connection: Connect Pin 8 to positive voltage and Pin 4 to ground (or negative rail).
- Input signals: Connect sensors or signal sources to Pin 3 (IN1+) and Pin 2 (IN1-) for first channel, or Pins 5 and 6 for second channel.
- Output load: Connect output loads to Pin 1 or Pin 7. Avoid shorting to ground or supply.
- Negative feedback (for linear amplification): Add a resistor between output (Pin 1) and inverting input (Pin 2).
- Decoupling: Place a 100nF capacitor between Pin 8 and Pin 4 as close to the IC as possible.
What is the INX IN518?
The "INX" prefix typically refers to Innolux (formerly a subsidiary of Foxconn), a major manufacturer of TFT-LCD panels. The IN518 is most likely a dedicated DC-DC converter or a Gamma reference buffer designed specifically for TFT-LCD source drivers.
