TPS60231RGTR from Texas Instruments, in a VQFN-16-EP(3x3). 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 | ISET | input | Connect a resistor between this pin and GND to set the maximum current through the LEDs; recommended ISET current range is 4 µA to 130 µA. |
| 2 | NC | unconnected | No internal connection. |
| 3 | NC | unconnected | No internal connection. |
| 4 | D3 | input | Current sink input; connect the cathode of a white LED here, up to 25 mA per sink. |
| 5 | D2 | input | Current sink input; connect the cathode of a white LED here, up to 25 mA per sink. |
| 6 | D1 | input | Current sink input; connect the cathode of the first white LED here (the LED with highest forward voltage), up to 25 mA; D1 voltage is used to regulate VOUT. |
| 7 | PGND | power_in | Power ground. |
| 8 | VOUT | power_out | Charge pump output; connect the output capacitor (0.47 to 1 µF) and the anode of the LEDs to this pin, with overvoltage limit of 5.5 V typical. |
| 9 | C2+ | passive | Connect to the flying capacitor C2 (0.22 to 0.47 µF). |
| 10 | C1+ | passive | Connect to the flying capacitor C1 (0.22 to 0.47 µF). |
| 11 | C1- | passive | Connect to the flying capacitor C1 (0.22 to 0.47 µF). |
| 12 | C2- | passive | Connect to the flying capacitor C2 (0.22 to 0.47 µF). |
| 13 | VIN | power_in | Supply voltage input, 2.7 V to 6.5 V operating range. |
| 14 | GND | power_in | Analog ground. |
| 15 | EN1 | input | Enable input; logic high (above 1.3 V) enables the converter, and logic low with EN2 low forces shutdown with supply current under 1 µA; also used for PWM or digital dimming. |
| 16 | EN2 | input | Enable input for PWM dimming (0 to 50 kHz) or 4-step digital dimming with EN1; logic high above 1.3 V enables the converter. |
| 17 | PowerPAD | passive | Exposed thermal pad; connect with PGND and GND and solder to the board for thermal performance. |
