Inx | In518 Ic Pinout Diagram Top ((install))

Assuming a standard 8-pin SOIC/SSOP or 6-pin SOT package (verify with datasheet for exact package), a common top-view pin mapping pattern is shown conceptually here — replace pin names with those from the official datasheet before PCB layout:

| Pin No. | Pin Name | Function Description | | :--- | :--- | :--- | | | EN | Enable Pin: Active high. Logic high (>1.2V) enables output. Tie to VIN if unused. | | 2 | GND | Ground: Common reference for input and output. Connect to system ground plane. | | 3 | IN | Input Voltage: Unregulated supply input. Bypass with a 1µF – 10µF ceramic capacitor to GND. | | 4 | BYPASS / NR | Bypass/Noise Reduction: Connect a 10nF – 100nF capacitor to GND to reduce output noise. | | 5 | NC / FB | No Connect or Feedback: On fixed-output versions, this pin is NC. On adjustable versions, it connects to a resistor divider. | | 6 | OUT | Regulated Output: Provides stable output voltage. Needs a 1µF – 10µF capacitor to GND. | inx in518 ic pinout diagram top

Provides the high-voltage supply (often around 17V) for the source driver. Assuming a standard 8-pin SOIC/SSOP or 6-pin SOT

Beyond the DC-DC converter, the IN518 works in concert with other specialized ICs. On a typical T-Con board, you will frequently find the IN518 paired with: Tie to VIN if unused

| IC | Package Top View | TX/RX Max | I2C Speed | |---------|------------------|-----------|-----------| | IN518 | QFN-48, 7x7mm | 12/12 | 400 kHz | | IN520 | QFN-64, 9x9mm | 16/20 | 1 MHz | | IN505 | QFN-32, 5x5mm | 8/8 | 400 kHz |

This pin delivers the operating voltage to the internal control circuitry of the IC. It requires a stable DC voltage within the chip's specified datasheet limits. A small ceramic bypass capacitor is usually placed close to this pin to filter out high-frequency noise.
