LM25011AMY from Texas Instruments, in a HVSSOP-10. 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 | VIN | power_in | Input supply voltage with an operating range of 6 V to 42 V and a 45 V transient capability; a low-ESR capacitor must be placed as close as possible to the VIN and SGND pins. |
| 2 | RT | input | On-time control: an external resistor from VIN to this pin sets the buck switch on-time and the switching frequency. |
| 3 | PGD | output | Power-good logic output that indicates when the FB voltage has risen above 95% of the internal reference, with hysteresis; an external pull-up resistor to a voltage less than 7 V is required. |
| 4 | SS | input | Soft-start pin: an internal current source charges an external capacitor to provide the soft-start function. |
| 5 | SGND | power_in | Signal ground for all internal circuitry other than the current limit sense circuit. |
| 6 | FB | input | Feedback input connected internally to the regulation comparator, with a regulation level of 2.51 V. |
| 7 | CSG | power_in | Current sense ground: connect to ground and to the current sense resistor for the current limit sensing circuit. |
| 8 | CS | input | Current sense input: connect to the current sense resistor and the anode of the free-wheeling diode. |
| 9 | SW | output | Switching node connected internally to the buck switch source; connect to the external inductor, the cathode of the free-wheeling diode, and the bootstrap capacitor. |
| 10 | BST | input | Bootstrap capacitor connection for the buck switch gate driver; connect a 0.1 µF capacitor from SW to this pin, charged during the buck switch off-time via an internal diode. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
