TPS62161DSGT 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 pin for the converter's power stage. |
| 2 | VIN | power_in | Supply voltage input with a recommended range of 3 V to 17 V and an absolute maximum of 20 V. |
| 3 | EN | input | Enable input where High enables the device and Low disables it; DC voltage must stay between -0.3 V and VIN + 0.3 V. |
| 4 | AGND | power_in | Analog ground pin, to which the exposed thermal pad must be connected. |
| 5 | FB | input | Voltage feedback pin; the TPS62161 is a fixed 1.8 V version, so the datasheet recommends connecting FB to AGND for improved thermal performance, with an absolute maximum range of -0.3 V to 7 V. |
| 6 | VOS | input | Output voltage sense pin and connection for the control loop circuitry, rated -0.3 V to 7 V. |
| 7 | SW | output | Switch node connected to the internal MOSFET switches, where the inductor connects between SW and the output capacitor; DC range is -0.3 V to VIN + 0.3 V and AC (less than 10 ns) range is -2 V to 24.5 V. |
| 8 | PG | output | Open-drain power good output that is High when VOUT is ready and Low when VOUT is below nominal regulation, requiring a pull-up resistor, with a maximum sink current of 10 mA. |
| 9 | Exposed Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
