TPS62170DSGT 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 return for the internal low-side power MOSFET. Must be tied to the ground plane with a low-impedance path close to the input capacitor. |
| 2 | VIN | power_in | Supply voltage input, 3 V to 17 V (absolute max 20 V). Bypass with a low-ESR ceramic input capacitor (typically 10 µF) placed close to the pin. |
| 3 | EN | input | Enable input. High (>0.9 V) turns the converter on; low (<0.3 V) puts the device in shutdown (<2 µA). Do not leave floating; can be tied to VIN for auto-start. |
| 4 | AGND | power_in | Analog ground reference for the internal control circuitry. Must be tied to PGND at a single low-noise point (typically the thermal pad). |
| 5 | FB | input | Voltage feedback input for the adjustable version (TPS62170). Connect a resistive divider from VOUT to set the output voltage; internal reference is 0.8 V typical. On fixed-output variants (TPS62171/72/73) TI recommends tying FB to AGND for improved thermal performance. |
| 6 | VOS | input | Output voltage sense pin used by the DCS-Control loop. Connect directly to VOUT at the output capacitor for accurate regulation and fast transient response. |
| 7 | SW | output | Switch node connected to the internal high-side and low-side power MOSFETs. Connect the external inductor (typically 2.2 µH) between SW and the output capacitor. Keep this trace short to minimize EMI. |
| 8 | PG | output | Power-good open-drain output. High-impedance when VOUT is within regulation (>=95% rising, >=90% falling); pulled low when out of regulation. Requires an external pull-up resistor (typically 100 kΩ) to a logic rail; max sink current 10 mA. Goes high-impedance when the device is disabled. |
| 9 | EP | power_in | Exposed thermal pad on the package underside. Must be soldered to the PCB and connected to AGND for proper power dissipation and mechanical reliability. |
