Enables or disables the IC; a logic-level input.
Understanding the physical constraints of the IN518 is the first step in handling it correctly. inx in518 ic pinout diagram top
The (also identified as 1N518 ) is a multi-channel DC-to-DC converter IC primarily used in Innolux LCD TV T-CON boards and panel display modules. It typically comes in a QFN-40 (Quad Flat No-lead) surface-mount package. Pinout Configuration (Top View)
The IN518's reliability makes it a "game-changer" for various display-dependent technologies: LCD monitor boards, power supplies, LED drivers, portable
Unlike a chip which might have a "Pin 1" indicator like a dot or notch, the diode identifies its outputs via this band.
If you are diagnosing a board featuring the , use the following troubleshooting steps: Check Pin 2 (VIN): Ensure the input voltage is present. The (also identified as 1N518 ) is a
Note: The IN518 is a proprietary, custom-programmed chip. While the pin numbering follows the standard QFN layout, the specific functions may vary slightly depending on the customer code (e.g., IN518-NT02, IN518-N03). The data below represents the most common configuration found on T-Con boards.
IC enable pin; high enables the device, low puts it in shutdown mode. Pin 4 (GND): Ground reference for the entire IC. Pin 5 (GND): Ground reference (often tied with pin 4). Pin 6 (SW/OUT): Switching output or power output node.
