Found on panels like the Innolux V236BJ1-P01 and similar small-to-medium LED TV screens.
Features built-in overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown (TSD).
Overcurrent protection (1.5A threshold) and thermal shutdown. Switching Frequency: ~1.1MHz. Inx In518 IC Pinout Diagram (QFN-16 Typical Configuration)
Understanding the pinout is essential for troubleshooting common display issues like "No Display" or "Backlight OK, No Image". While it is often an internal OE component with limited public documentation, schematic diagrams reveal key connection points:
Despite the manufacturer (INX) not having released a comprehensive public datasheet, the collective knowledge of electronics engineers and repair technicians has mapped out the critical functions of the IN518 pins. Because the chip is a PMIC, the pins are generally categorized into four main groups: Power Input, Power Output (Generated Rails), Control/Signaling, and Feedback. Inx In518 Ic Pinout Diagram

Controls the operational state of the IC. Driving this pin high or low shifts the chip between active execution mode and ultra-low-power standby mode.
Enable/Chip Enable input. Driving this pin high activates the IC, while pulling it to ground places the chip into ultra-low-current standby mode. COMP
If you can provide the package type (Black chip vs. Glass tube), I can refine the pinout diagram further.
To understand why the IN518 is so important, it helps to see how it fits into the larger system. On the T-CON board, it's typically one of several key ICs that work together: INNOLUX Panel Backlight ok No display,,in518 DC to
for 32" to 50" LED/LCD TVs (e.g., Innolux panels). Handheld Meters and digital clocks.
This comprehensive guide provides not only the detailed pinout configuration but also delves into the IC’s internal architecture, voltage specifications, common applications, and troubleshooting tips.
(also identified as ) is a specialized DC-to-DC converter IC primarily used in LCD display panels
Clean the PCB pads with isopropyl alcohol and apply a small amount of no-clean solder paste.
Because the In518 performs complex multi-rail distribution (handling high-voltage backlight power alongside sensitive logic biasing), the pinout is clustered by subsystem function. When looking at the chip top-down with the index pin dot or chamfered corner positioned at the top-left, the pins increase sequentially in a counter-clockwise direction: Pin Cluster / Rails Primary Node Designation Functional Description 3.3V / VCC Primary logic voltage supply input.

When building an FPGA or microcontroller-based LCD driver, the IN518 can act as a simple timing generator. The pinout allows direct connection to common MCUs like STM32 or Arduino Due.
