Operating Temperature: Rated for industrial use between -40°C and +85°C.
Functionality: Acts as a critical Display Driver IC or DC-DC converter, often found in T-CON boards for LCD panels. IN518 Pinout Configuration (QFN-16)
While specific internal pin assignments can vary slightly by manufacturer, the standard top-view configuration for a QFN-16 LCD driver IC like the IN518 typically includes the following functional pins: Description Power (VCC/VDD)
Supplies the necessary 3.3V to power the internal logic and display circuitry. Ground (GND)
Common ground connection for the chip, often connected to the central thermal pad. Input Signals
Receives timing and data signals from the main controller or T-CON. Output Channels
Sends processed voltage levels to the LCD panel pixels for image rendering. Feedback/Control
Used for monitoring output stability and adjusting voltage levels (FB pins). Common Applications
The IN518's reliability makes it a "game-changer" for various display-dependent technologies:
Consumer Electronics: Handheld meters, digital clocks, and small-screen gadgets. Medical Equipment: Monitors and diagnostic display panels.
Industrial Automation: Control panels that require low-power, high-stability display drivers.
LCD Repair: Frequently replaced in Innolux panels when "No Display" or backlight issues occur. Troubleshooting and Repair The INX IN518 is an integrated circuit commonly
In repair scenarios, such as those documented by technicians on YouTube, the IN518 is a common culprit for screen failure.
Visual Inspection: Check for burn marks or cracked casing on the QFN package. Voltage Check: Verify that 3.3V is present at the VCC pins.
Continuity: Use a multimeter to ensure no short circuits exist between pins, especially the ground pad.
Replacement: If the display is black but the backlight is functional, replacing the IN518 often restores signal routing to the pixels.
For further procurement, you can find the IN518 IC through global distributors such as AliExpress, Worldway Electronics, and IndiaMART.

(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
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:
Connected to an external AVDD coil; it handles the internal switching to generate the primary boost voltage. High Voltage Outputs (AVDD/H-AVDD): Generates output voltages (often around ) required for driving the LCD panel. Gate Drive Output:
Uses an internal or external MOSFET to drive the "all gate" (COF) supply lines. Feedback/Protection Pins: Place C1 and C2 as close as possible
Monitor for shortages; if a shortage occurs on the output, these pins can trigger a protection mode to prevent board damage. Key Specifications & Features Package Type:
(6x6mm approximately) designed for space-constrained T-CON boards. Applications: Primarily used in Innolux (INX)
and other LCD panels for signal conditioning, voltage regulation, and power management. Common Versions:
Variants include T01, T02, T03, and NT02, which represent specific hardware revisions or performance improvements. Troubleshooting Insights Short Circuit Faults:
Shortages in the output lines often lead to "no display" faults. If the AVDD voltage is missing, check the input 12V and the switching coil. Heat Sensitivity:
Some technicians report that applying heat to the IC can temporarily resolve certain internal logic issues, though this is usually a diagnostic step rather than a permanent fix.

Here is the proper top-down pinout diagram for the INX (InnoSenT) IN518 radar motion sensor IC, with pin numbering and covering description.
Important note: IN518 is a QFN-32 package (5x5 mm). Pin 1 is indicated by a dot or chamfered edge on the top of the IC.
PCB Layout Tips:
- Place C1 and C2 as close as possible to the IN and OUT pins (within 5mm).
- Use a solid ground plane – The GND pin (pin 2) should have a direct via to ground.
- Keep bypass cap leads short – For pin 4, the 100nF cap should be close to the IC.
- Thermal management – If operating near 300mA, add thermal vias under the IC.
