Inx In518 Ic Pinout Diagram ((top)) File

| Pin # | Name | Typical Function | |-------|-----------|-----------------------------------------------------------| | 1 | EN | (Active High). Pull to VIN to turn on. | | 2 | COMP | Compensation (RC network to GND for loop stability). | | 3 | FB | Feedback (Resistor divider to set Vout). | | 4 | GND | Ground (Power and signal ground). | | 5 | SW | Switching Node (Connect to inductor and diode/catch). | | 6 | VIN | Input Voltage (Typically 4.5V to 18V absolute max). | | 7 | VCC | Internal LDO output (Often 5V for gate drive). | | 8 | SS | Soft-Start (Capacitor to GND sets startup ramp). |

While specific manufacturer datasheets for "Inx" brand components can be proprietary, typical pin configurations for this class of 8-pin power regulator ICs are as follows: Pin Number Description Main input voltage (Supply for the IC). Ground reference for the circuit. Enable pin; pulls high to turn the IC on. Feedback pin; used to set/sense the output voltage level. Regulated voltage output or switching node to inductor. Boost or internal power supply bypass pin. Compensation or Soft-Start control. NC / PGOOD Not connected or Power Good indicator signal. Common Applications LCD TV Repair: Inx In518 Ic Pinout Diagram

The is your roadmap to repairing or designing with one of the display industry’s versatile driver ICs. While the exact pin functions may vary slightly between revisions (IN518A, IN518B, etc.), the core groups—power, control, input data, and source outputs—remain consistent. | Pin # | Name | Typical Function

It is primarily responsible for generating regulated voltages required by the main processor (DSP), memory (DDR), or display panel logic. Package Type: It is commonly found in an (8-pin Small Outline Package) format. IN518 Pinout Description | | 3 | FB | Feedback (Resistor divider to set Vout)
