TPS62065QDSGRQ1 from Texas Instruments, in a WSON-8-EP(2x2). 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 | PGND | power_in | Ground supply pin for the output stage. |
| 2 | SW | tri_state | Switch pin connected to internal MOSFET switches with external inductor connected between this terminal and output capacitor. |
| 3 | AGND | power_in | Analog ground supply pin for the control circuit. |
| 4 | FB | input | Feedback pin for internal regulation loop connected to external resistor divider or directly to output capacitor. |
| 5 | EN | input | Enable pin pulled high to enable device and low for shutdown mode; must be terminated. |
| 6 | MODE | input | Mode selection pin pulled high for fixed frequency PWM mode or low for power save mode with automatic PFM/PWM transition; must be terminated. |
| 7 | AVIN | power_in | Analog power supply input for control circuit with supply range 2.9V to 6V. |
| 8 | PVIN | power_in | Power supply pin for output stage with supply range 2.9V to 6V. |
| 9 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
