– Feedback pin; used to set or monitor the output voltage. Pin 5: LX / SW – Switching output; connects to the external inductor. Pin 6: BST / VCC

: On the bottom side (underneath the top layout), a large exposed metallic thermal pad serves as the primary system ground ( GNDcap G cap N cap D ) and a heatsink to dissipate operating thermal energy. Core Functional Pinout Architecture

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: inx in518 ic pinout diagram top

The INX IN518 is most commonly manufactured in a compact or QFN-16 surface-mount package , featuring an exposed thermal pad on the bottom for heat dissipation.

The INX IN518 is most frequently encountered in a . This is a compact, surface-mount type with 40 connection pads arranged around a large, central thermal pad. This package is well-suited for space-constrained, high-density circuit boards. – Feedback pin; used to set or monitor the output voltage

To understand the IN518 's role, it helps to know where it's found. It is a key component on the , which acts as the interface between a TV's main processor and the LCD panel itself. Here, its job is to convert the board's input voltage (often 12V) into several highly accurate, regulated outputs required by the panel's row and column drivers. These outputs include essential supply rails like VGH (gate high voltage, often around 25-30V), VGL (gate low voltage, often around -5V to -8V), and VAA (analog supply, often around 15-18V).

Multiple pins tied to the internal ground plane to ensure signal stability and prevent electromagnetic interference (EMI). Core Functional Pinout Architecture One of the most

If you have a component labeled "INX IN518" and need to verify the pinout because the band is faded or the glass is dirty, use a Digital Multimeter (DMM).

As display technology evolves towards 4K, 8K, and OLED, the architecture of T-Con boards is shifting. However, for the vast install base of 1080p and 4K LCD TVs manufactured between 2018 and 2025, the IN518 will remain a crucial component. It represents a generation of highly integrated, cost-effective PMICs that simplified board design while centralizing the points of failure.
