# TPS62175DQCR

**Texas Instruments** · DC-DC Converters · WSON-10-EP(2x3)

TPS62175DQCR from Texas Instruments, in a WSON-10-EP(2x3). 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 for the converter, with a recommended operating range of 4.75 V to 28 V. |
| 3 | EN | input | Enable input (High = enabled, Low = disabled). |
| 4 | NC | unconnected | This pin is recommended to be connected to AGND but can be left floating. |
| 5 | FB | input | Voltage feedback of the adjustable version; connect a resistive divider to this pin, and TI recommends connecting FB to AGND for fixed-voltage versions for improved thermal performance. |
| 6 | AGND | power_in | Analog ground connection. |
| 7 | PG | output | Output power good (open drain, requires pullup resistor). |
| 8 | SLEEP | input | Sleep mode input (High = normal operation, Low = sleep mode operation), which can be operated dynamically during operation and should be connected to VOUT if sleep mode is not used. |
| 9 | SW | output | Switch node connected to the internal MOSFET switches; connect the inductor between SW and the output capacitor. |
| 10 | VOS | input | Output voltage sense pin and connection for the control loop circuitry. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
