**Texas Instruments** · DC-DC Converters · VQFN-16-EP(3x3)

TPS62132RGTR from Texas Instruments, in a VQFN-16-EP(3x3). 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 | SW | output | Switch node connected to internal MOSFET switches; connect inductor between SW and output capacitor |
| 2 | SW | output | Switch node connected to internal MOSFET switches; connect inductor between SW and output capacitor |
| 3 | SW | output | Switch node connected to internal MOSFET switches; connect inductor between SW and output capacitor |
| 4 | PG | tri_state | Open-drain power-good output; High when VOUT ready, Low when below nominal regulation; requires pullup resistor |
| 5 | FB | input | Voltage feedback input for adjustable versions; connect to AGND on fixed output voltage versions for improved thermal performance |
| 6 | AGND | power_in | Analog ground; must be connected directly to exposed thermal pad and common ground plane |
| 7 | FSW | input | Switching frequency select; Low ≈ 2.5 MHz, High ≈ 1.25 MHz for typical operation; internal pulldown if floating |
| 8 | DEF | input | Output voltage scaling; Low = nominal, High = nominal + 5%; internal pulldown if floating |
| 9 | SS/TR | input | Soft-start/tracking pin; external capacitor sets internal voltage reference rise time for tracking and sequencing |
| 10 | AVIN | power_in | Supply voltage for control circuitry; connect to same source as PVIN |
| 11 | PVIN | power_in | Supply voltage for power stage; connect to same source as AVIN |
| 12 | PVIN | power_in | Supply voltage for power stage; connect to same source as AVIN |
| 13 | EN | input | Enable input; High = enabled, Low = disabled; internal pulldown if floating |
| 14 | VOS | input | Output voltage sense pin and connection for the control loop circuitry |
| 15 | PGND | power_in | Power ground; must be connected directly to exposed thermal pad and common ground plane |
| 16 | PGND | power_in | Power ground; must be connected directly to exposed thermal pad and common ground plane |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
