ITE9107A28F4M from CHIPLINK(芯联), in a DFN1x1-4L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | power_out | Regulated output voltage, the power output of the device, with a 1.0uF ceramic capacitor recommended at this pin. |
| 2 | GND | power_in | IC ground. |
| 3 | EN | input | Enable pin: pulling it high enables and low disables the device (active high per the Enable section), and floating EN is not recommended. |
| 4 | VIN | power_in | Power supply voltage input, operating from 2.3V to 5.5V, with a 1.0uF ceramic capacitor recommended at this pin. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
