TPS62173DSGR 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 reference for switching currents. |
| 2 | VIN | power_in | Supply voltage input, rated operating range 3V to 17V. |
| 3 | EN | input | Enable input; logic high enables device operation, logic low forces shutdown with 1.5µA typical shutdown current and internal 400kΩ pull-down resistor. |
| 4 | AGND | power_in | Analog ground reference for control and feedback circuits. |
| 5 | FB | input | Voltage feedback input regulated to 0.8V internal reference; use resistor divider from output on adjustable version or connect to AGND on fixed voltage versions for improved thermal performance. |
| 6 | VOS | input | Output voltage sense input connected to error amplifier for output voltage regulation control. |
| 7 | SW | output | Switch node connected to internal high-side and low-side MOSFET bridges; maximum DC voltage VIN+0.3V, AC transient maximum 24.5V for durations <10ns. |
| 8 | PG | output | Open-drain power good output indicating output voltage regulation; high-impedance when VOUT ≥92% nominal, low (<0.3V) when below threshold; requires external pull-up resistor, maximum sink 2mA. |
| 9 | THERMAL_PAD | power_in | Exposed thermal dissipation pad electrically connected to AGND; must be soldered to achieve proper thermal performance and mechanical reliability. |
