TPS75105DSKT from Texas Instruments, in a DFN-10-EP(2.5x2.5). 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 | ENB | input | Enable pin for Bank B: high turns on the Bank B current source, low turns it off, and a PWM signal reduces LED current between 0 mA and the maximum set by ISET; can be left open or tied to GND if unused. |
| 2 | ENA | input | Enable pin for Bank A: high turns on the Bank A current source, low turns it off, and a PWM signal reduces LED current between 0 mA and the maximum set by ISET; can be left open or tied to GND if unused. |
| 3 | D1A | output | Diode source current output for Bank A, connect to LED anode. |
| 4 | D2A | output | Diode source current output for Bank A, connect to LED anode. |
| 5 | GND | power_in | Ground pin, connected together with the exposed thermal pad. |
| 6 | NC | unconnected | Not internally connected. |
| 7 | D2B | output | Diode source current output for Bank B, connect to LED anode. |
| 8 | D1B | output | Diode source current output for Bank B, connect to LED anode. |
| 9 | VIN | power_in | Supply input, recommended operating range 2.7 V to 5.5 V (absolute maximum 7 V). |
| 10 | ISET | input | Optional resistor to GND sets the maximum LED current; if no resistor is connected, it defaults to the internally programmed value. |
| 11 | GND | power_in | Exposed thermal pad, ground (listed as 'Pad' together with pin 5). |

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