Inx In518 Ic Pinout Diagram Top ✅

The is a specialized, surface-mount DC-to-DC converter and power management chip primarily designed for LCD panel timing controllers (T-CON boards) and white LED backlight drivers . Commonly deployed in consumer electronics such as TVs, monitors, and handheld display units, this integrated circuit is engineered within a compact QFN (Quad Flat No-leads) package—most frequently found in QFN-40 or QFN-16 variants depending on the specific hardware generation (e.g., T01, T02, or T03 revisions). It functions as a synchronous boost converter that translates a main supply voltage (typically a single Li-ion cell range of 2.7V–5.5V or a 12V board line) into stable, multi-channel outputs necessary to drive liquid crystal displays and multiple series-connected LED backlights without flickering.

This collaborative ecosystem means that a board-level fault could reside in any of these components. If IN518 voltages are good but no image is present, the problem could lie with the timing controller or the level shifter.
