Often labeled as "No Connection" or used for specialized startup/sensing functions depending on the specific manufacturer's implementation. Technical Resources Looking at the glass body from the 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) Technical Resources The (also identified as 1N518 )
Typically available in a QFN-16 (Quad Flat No-leads) package, measuring approximately 4mm x 4mm with a 0.5mm pitch. Operating Voltage: Operates on a standard 3.3V supply .
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
