Inx In518 Ic Pinout Diagram Top Jun 2026

The IN518 is frequently identified as the root cause of many LCD panel failures due to the high voltages and thermal stress it handles. Common failure symptoms include:

One of the most confusing aspects for technicians is the chip's "top marking." The reported markings vary, leading to doubts about compatibility. Confirmed markings include:

The INX IN518 IC is widely used in various applications, including: inx in518 ic pinout diagram top

The (also often identified as the IN518 ) is a multi-channel power management integrated circuit (PMIC) typically used in LCD TV control boards (T-CON) to generate the various supply voltages required for the display panel. Core Features

Gamma correction output voltages that correspond to specific grey levels. 4. Key Applications of the INX IN518 The IN518 is frequently identified as the root

If you are looking for this diagram, you are likely dealing with a "No Display" or "Backlight OK, No Picture" issue on an Innolux LED/LCD TV panel. Check Input: is present at Pin 4 (through the fuse). Verify Output Boosts: Use a multimeter to check for AVDD (17V) at their respective test points near the IC. Signal Lines: This IC is often used alongside level shifters (like the

Multiple channels (e.g., G1–G14, G1–G18) that generate the gamma reference voltages for the source driver ICs. Check Input: is present at Pin 4 (through the fuse)

Provides the high-voltage supply (often around 17V) for the source driver.
