Inx In518 Ic Pinout Diagram Top <2024-2026>

: Often utilizes a large center thermal pad (Exposed Pad) which must be soldered to the PCB ground for heat dissipation.

When viewed from the , the INX IN518 features a square body layout. Most common iterations, such as the INX IN518 QFN-40 package listed on AliExpress, feature 40 connection pads tucked under the edges of the silicon body, surrounding a central thermal ground pad.

VDD (3.3V typical), AVDD (17V or similar, depending on panel design).

The INX IN518 IC has a standard 8-pin configuration, which is depicted in the following pinout diagram:

Integrates step-up converters (Boost), step-down regulators (Buck), charge pump controllers, and a Gamma buffer array. INX IN518 Pinout Diagram Configuration (Top View)

Interpreting the physical layout of the QFN-40 package is crucial for manual inspection and multimeter probing. Below is a textual representation of the pinout as seen from the top (component side) with the orientation mark located at Pin 1. : Often utilizes a large center thermal pad

A boost voltage for the panel's analog circuitry, often around 15V to 17V VCOM / Gamma Voltages:

The pin is tied to a microcontroller or hardware switch to handle power states. PCB Layout and Thermal Considerations

VGH is reading 0.3V instead of ~30V.

Repair guides often highlight that locating the and diodes near the IC is the best starting point for reverse-engineering. By following the traces from the chip to these components, you can often identify the switching output pins and correlate them with specific output voltages.
