TPS75105DSKR 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; accepts PWM signal to modulate LED current from 0 mA to ISET maximum. |
| 2 | ENA | input | Enable pin for Bank A; accepts PWM signal to modulate LED current from 0 mA to ISET maximum. |
| 3 | D1A | output | Diode current source output for Bank A; supplies constant current 3-25 mA to LED anode. |
| 4 | D2A | output | Diode current source output for Bank A; supplies constant current 3-25 mA to LED anode. |
| 5 | GND | power_in | Ground reference; includes pin 5 and exposed thermal pad. |
| 6 | NC | unconnected | Not internally connected. |
| 7 | D2B | output | Diode current source output for Bank B; supplies constant current 3-25 mA to LED anode. |
| 8 | D1B | output | Diode current source output for Bank B; supplies constant current 3-25 mA to LED anode. |
| 9 | VIN | power_in | Supply input voltage; accepts 2.7-5.5 V per recommended operating conditions. |
| 10 | ISET | input | Resistor connection for LED current setting; defaults to factory-programmed value (5 mA for TPS75105) if not connected. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
