The is a highly specialized, surface-mount display power management and timing controller chip widely deployed in modern LCD/LED television panels and monitor T-CON (Timing Controller) boards . Manufactured primarily for high-density display assemblies like Innolux panels, this integrated circuit is crucial for generating the fundamental supply rails—such as VGH, VGL, AVDD, and DVDD—required to actuate thin-film transistors (TFTs) across a display grid. Because it manages delicate high-frequency switching nodes right alongside highly sensitive signal lines, understanding its exact top-view pin configuration is essential for television repair technicians, hardware engineers, and display component developers alike. inx in518 ic pinout diagram top

⚠️ Always verify with the , as InnoSenT may have released multiple revisions with slight pin assignment changes (especially on I/Q output pins or clock input).

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 Supplies the necessary 3

Low-level gate drive voltage (negative voltage, e.g., -5V to -7V). 3.3V / VCC: Internal logic or secondary output voltage. Control signal to turn the IC functions on/off. Pins dedicated to the gamma correction reference voltages. Drafting Guide: Troubleshooting & Identification Locate Pin 1

: Identified by a circular dot or indentation at the top-left of the IC. or a "white screen" effect

: A faulty IN518 often results in "no display" issues, screen flickering, ghosting, or backlight-only conditions where the screen remains blank despite the lights being on. Availability Inx In518 Ic Pinout Diagram TOP | PDF - Scribd

The IN518 is most commonly used in of television T-CON boards. When a TV has sound but no picture, or a "white screen" effect, technician's often check the output voltages of the IN518 to ensure the display panel is receiving its necessary power.
