TPS62172DSGR from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PGND | power_in | Power ground for high-current switching path. |
| 2 | VIN | power_in | Supply voltage input with operating range 3 V to 17 V per Recommended Operating Conditions section 7.3. |
| 3 | EN | input | Enable input; high enables device operation, low disables with typical shutdown current of 1.5 µA and internal pull-down resistor of approximately 400 kΩ. |
| 4 | AGND | power_in | Analog ground reference that must be connected to exposed thermal pad. |
| 5 | FB | input | Voltage feedback input for adjustable versions; for fixed TPS62172 output version, internally pulled down and recommended to connect to AGND for improved thermal performance. |
| 6 | VOS | input | Output voltage sense input for internal control loop circuitry providing fast transient response and output regulation. |
| 7 | SW | output | Switch node connected to internal MOSFET switches; connect inductor between SW and output capacitor for DC-DC conversion. |
| 8 | PG | tri_state | Open-drain power good output indicator; high impedance when VOUT ready (≥92% nominal regulation), low when below regulation (≤87% nominal), can sink 2 mA and requires external pull-up resistor. |
| 9 | Exposed Thermal Pad | power_in | Electrical connection to AGND that must be soldered to printed circuit board for mechanical reliability and thermal dissipation; junction-to-board thermal resistance RθJB is 15.5 °C/W per section 7.4. |
