Inx In518 Ic Pinout Diagram Top -

(also often marked simply as ) is a 6-pin SMD power management or DC-DC step-down converter IC, frequently used in the T-CON boards of LCD and LED televisions, such as those from Chi Mei Innolux (INX). Pinout Configuration (Top View)

Pin numbering convention (top view, notch or dot indicates pin 1): inx in518 ic pinout diagram top

• Left Lead (Anode): Connects to the positive side of the voltage source or the signal path.
• Right Lead (Cathode): Marked by the band. Connects to ground or the negative side of the load.

VGH (Gate High): High positive voltage for switching TFT gates on. (also often marked simply as ) is a

Specific pinout details for the "TOP" view (how the pins are numbered when looking down at the component on a PCB) generally follow these standards for small-form ICs: Package Type Left Lead (Anode): Connects to the positive side

Scenario A: Correct Installation

• Connection: Anode to Signal Source, Cathode to Load.
• Result: The signal passes through. The diode acts as a switch (closed).
• Voltage Drop: The signal voltage is reduced by approximately 0.7V to 1V.

Repair Tip: Always verify the 12V input at Pin 4 first. If the input is present but there is no VGH or VGL output, the IC may be faulty or there could be a short circuit in the panel's CKV lines.
