TPS65105RGER 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, to which a small capacitor is connected. |
| 2 | ENR | input | Enable pin of the linear regulator controller; it must be terminated and not left floating, with logic high enabling the regulator and logic low putting it in shutdown. |
| 3 | EN | input | Enable pin of the device; it must be terminated and not left floating, with logic high enabling the device and logic low shutting it down. |
| 4 | FB1 | input | Feedback pin of the boost converter (VO1). |
| 5 | FB4 | input | Feedback pin of the linear regulator controller, which is set to a fixed output voltage of 3.3 V or 3 V depending on the version. |
| 6 | BASE | output | Base drive output for the external transistor; if the linear regulator is not needed, this pin should be pulled against VIN. |
| 7 | VIN | power_in | Input voltage pin of the device, with a recommended input range of 2.7 V to 5.8 V and an absolute maximum of 6 V. |
| 8 | SW | passive | Switch pin of the boost converter, with an absolute maximum voltage of 20 V on the SW pin. |
| 9 | SW | passive | Switch pin of the boost converter, with an absolute maximum voltage of 20 V on the SW pin. |
| 10 | PGND | power_in | Power ground, to which the PowerPAD or exposed thermal die must be connected. |
| 11 | PGND | power_in | Power ground, to which the PowerPAD or exposed thermal die must be connected. |
| 12 | SUP | power_in | Supply pin of the positive and negative charge pumps, boost converter gate drive circuit and VCOM buffer; it must be connected to the output of the main boost converter and cannot be connected to any other voltage source. |
| 13 | VCOM | output | VCOM buffer output. |
| 14 | VCOMIN | input | Positive input terminal of the VCOM buffer; when the VCOM buffer is not used, it can be connected to GND to reduce the overall quiescent current of the IC. |
| 15 | FB3 | input | Feedback pin of the positive charge pump. |
| 16 | OUT3 | output | Positive charge pump output (VO3), with an absolute maximum voltage of 30 V. |
| 17 | C2+ | passive | Positive terminal of the charge pump flying capacitor; this pin should be left open if the device runs in voltage doubler mode. |
| 18 | C2-/MODE | passive | Negative terminal of the charge pump flying capacitor and charge pump MODE pin; a flying capacitor connected here gives voltage tripler mode, while for doubler mode the capacitor is removed and this pin is connected to GND. |
| 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, with an absolute maximum voltage of 15 V. |
| 22 | GND | power_in | Ground. |
| 23 | REF | output | Internal reference output, typically 1.23 V. |
| 24 | FB2 | input | Feedback pin of the negative charge pump. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
