While specific pin functions can vary slightly by application (e.g., as a LED driver or buck converter), a typical 6-pin power IC configuration for this series includes: — System ground.

While an official datasheet is not publicly available from INX, field measurements and repair forum discussions have established a reliable set of operational parameters. The chip is powered by a 12V supply on the T-Con board and internally regulates and boosts voltages as follows:

Toggles active/standby states and manages display panel brightness. Reference Ground

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.

Notes:

The IN518 is most commonly housed in a or 5-pin SOT-23-5 package. Below is the standard pinout diagram for the SOT-23-6 variant, viewed from the top .

The most common misinterpretation is between and "1N518" . On the tiny surface of a QFN package, the serif font often makes the letter "I" look exactly like the number "1". Searching for "1N518" instead of "IN518" will lead to incorrect results and potential misdiagnoses. from pin 1 marker) While specific pin functions

Check if the output voltages match the panel specs.

While no official pinout diagram is available, cross-referencing repair guides and technical discussions allows us to categorize the majority of the pins into functional groups:

High frequency (often >500kHz) to allow for smaller inductors and capacitors. 5. Troubleshooting the INX IN518

Sourcing and replacing the IN518 is not as straightforward as replacing a 555 timer. Package Variations and Top View Orientation Notes: |

The (also referred to as 1N518) is a specialized DC-to-DC power management and display driver IC primarily used in LCD and LED TV T-CON (Timing Controller) boards. It is most commonly found in compact consumer electronics and industrial panels to handle critical functions like signal timing, voltage level shifting, and pixel data routing. Key Specifications & Identification

The is a highly specialized, multi-channel DC-to-DC power management and gamma reference integrated circuit primarily utilized on T-CON (Timing Controller) boards in LCD and LED television display panels .
