LM3489MM from Texas Instruments, in a VSSOP-8-0.65mm. 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 | ISENSE | input | The current sense input must be connected to the PFET drain terminal directly or through a series resistor up to 600 Ω for 28 V > VIN > 35 V (limit as printed in the datasheet). |
| 2 | GND | power_in | Signal ground for the controller. |
| 3 | EN | input | Enable pin: connect to ground to shut down the part or float to enable operation (internally pulled high and clamped at 8 V typical); recommended EN voltage is 5.5 V maximum, and it can also be used for a UVLO function. |
| 4 | FB | input | Feedback input; connect to a resistor voltage divider between the output and GND to set the adjustable output voltage. |
| 5 | ADJ | input | Current limit threshold adjustment pin tied to an internal 5.5 µA current source; a resistor between this pin and VIN sets the overcurrent threshold compared against the ISENSE voltage. |
| 6 | PGND | power_in | Power ground for the external PFET gate drive. |
| 7 | PGATE | output | Gate drive output for the external PFET, which swings between VIN and VIN minus 5 V. |
| 8 | VIN | power_in | Power supply input pin; recommended VIN supply range is 4.5 V to 35 V. |
