TPS65145RGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 | COMP | passive | Compensation pin for the main boost converter with a small capacitor connected for stability. |
| 2 | ENR | input | Enable pin of the linear regulator controller; logic high enables and logic low puts the regulator in shutdown. |
| 3 | EN | input | Enable pin of the device; logic high enables and logic low shuts down the device. |
| 4 | FB1 | input | Feedback pin of the boost converter. |
| 5 | FB4 | input | Feedback pin of the linear regulator controller set to fixed output voltage of 3.3 V or 3 V depending on device version. |
| 6 | BASE | output | Base drive output for the external transistor. |
| 7 | VIN | power_in | Input voltage pin of the device operating from 2.7 V to 5.8 V. |
| 8 | SW | input | Switch pin of the boost converter connecting to external inductor and diode. |
| 9 | SW | input | Switch pin of the boost converter connecting to external inductor and diode. |
| 10 | PGND | power_in | Power ground connection. |
| 11 | PGND | power_in | Power ground connection. |
| 12 | SUP | power_in | Supply pin for positive and negative charge pump, boost converter, and gate drive circuit that must connect to main boost converter output only. |
| 13 | PG | output | Open-drain power good output indicating when all outputs VO1, VO2, VO3 are within 10% of nominal voltage, going low when one output falls below 10% of nominal voltage. |
| 14 | GND | power_in | Ground connection. |
| 15 | FB3 | input | Feedback pin of positive charge pump. |
| 16 | OUT3 | output | Positive charge pump output. |
| 17 | C2+ | passive | Positive terminal for the charge pump flying capacitor that must be left open for voltage doubler mode operation. |
| 18 | C2-/MODE | passive | Negative terminal of the charge pump flying capacitor and MODE pin; flying capacitor connection enables voltage tripler mode while connection to GND enables voltage doubler mode. |
| 19 | C1+ | passive | Positive terminal of the charge pump flying capacitor. |
| 20 | C1- | passive | Negative terminal of the charge pump flying capacitor. |
| 21 | DRV | output | External charge pump driver output. |
| 22 | GND | power_in | Ground connection. |
| 23 | REF | output | Internal reference output with typical value of 1.23 V. |
| 24 | FB2 | input | Feedback pin of negative charge pump. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
