In518 Ic Pinout Diagram Top !!better!!: Inx

: Negative voltage for switching TFT gates off. AVDD : Analog supply for the source driver.

| 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
