# TPS62170QDSGTQ1

**Texas Instruments** · DC-DC Converters · WSON-8-EP(2x2)

TPS62170QDSGTQ1 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 connection |
| 2 | VIN | power_in | Supply voltage input; absolute maximum rating 20V; recommended operating range 3V to 17V |
| 3 | EN | input | Enable input; High = enabled, Low = disabled; voltage range -0.3V to VIN+0.3V |
| 4 | AGND | power_in | Analog ground reference; must also be soldered to exposed thermal pad for proper dissipation and mechanical reliability |
| 5 | FB | input | Feedback input for adjustable output version; connect resistive voltage divider to set output voltage; for fixed output versions connect to AGND for improved thermal performance; voltage range -0.3V to 7V |
| 6 | VOS | input | Output voltage sense input for control loop feedback; voltage range -0.3V to 7V |
| 7 | SW | output | Internal MOSFET switch node; connect inductor to output capacitor for DC/DC conversion; voltage range -0.3V to VIN+0.3V |
| 8 | PG | tri_state | Power good open-drain output; High = VOUT ready, Low = VOUT below nominal regulation; requires external pull-up resistor; goes high-impedance when device switched off; voltage range -0.3V to 7V |
| 9 | Exposed Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
