TLV62090RGTT from Texas Instruments, in a QFN-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 | SW | bidirectional | Switch pin of the power stage (datasheet classifies it as I/O); pins 1 and 2 are both SW. |
| 2 | SW | bidirectional | Switch pin of the power stage (datasheet classifies it as I/O); pins 1 and 2 are both SW. |
| 3 | DEF | input | Used for internal logic and needs to be pulled high; it should not be left floating. |
| 4 | PG | output | Open-drain power good output that is high impedance when the output is within regulation and pulled low when below nominal; the pull-up resistor must not be connected to any voltage higher than the device input voltage. |
| 5 | FB | input | Feedback pin; connect a resistor divider to set the output voltage. |
| 6 | AGND | power_in | Analog ground; the exposed thermal pad is connected to AGND. |
| 7 | CP | bidirectional | Internal charge pump flying capacitor; connect a 10 nF capacitor between CP and CN. |
| 8 | CN | bidirectional | Internal charge pump flying capacitor; connect a 10 nF capacitor between CP and CN. |
| 9 | SS | input | Soft-start control pin; a capacitor on this pin sets the soft-start time, and leaving it floating sets the minimum start-up time. |
| 10 | AVIN | power_in | Bias supply input voltage pin. |
| 11 | PVIN | power_in | Power supply input voltage pin; input voltage range is 2.5 V to 5.5 V. |
| 12 | PVIN | power_in | Power supply input voltage pin; input voltage range is 2.5 V to 5.5 V. |
| 13 | EN | input | Device enable; must be pulled high to enable the device and pulled low to disable it, with an internal pull-down of typically 400 kΩ active when EN is low. |
| 14 | PGND | power_in | Power ground connection. |
| 15 | PGND | power_in | Power ground connection. |
| 16 | VOS | input | Output voltage sense pin; must be connected to the output voltage. |
| 17 | Exposed Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
