TPS62172QDSGRQ1 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 | Power ground. |
| 2 | VIN | power_in | Supply voltage input, 3V to 17V. |
| 3 | EN | input | Enable input; High enables the device, Low disables it. |
| 4 | AGND | power_in | Analog ground. |
| 5 | FB | input | Voltage feedback input; for fixed output versions (TPS62172-Q1), connect to AGND for improved thermal performance. |
| 6 | VOS | input | Output voltage sense pin for control loop feedback and regulation. |
| 7 | SW | output | Switch node connected to internal MOSFET switches; connect inductor between SW and output capacitor. |
| 8 | PG | tri_state | Power good output, open-drain type requiring pull-up resistor; High = VOUT ready (92-98% nominal), Low = VOUT below regulation. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
