TPS62142RGTR 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 driven by internal MOSFET switches; connect inductor between SW and output capacitor. |
| 2 | SW | output | Switch node driven by internal MOSFET switches; connect inductor between SW and output capacitor. |
| 3 | SW | output | Switch node driven by internal MOSFET switches; connect inductor between SW and output capacitor. |
| 4 | PG | tri_state | Open-drain power-good output (high-Z when VOUT ready, pulls low when VOUT below nominal regulation); requires external pullup resistor, max sink current 2 mA. |
| 5 | FB | input | Voltage feedback input for adjustable versions; connect to AGND on fixed-output TPS62142 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 input (low ≈ 2.5 MHz, high ≈ 1.25 MHz typical operation); internal ~400 kΩ pulldown resistor. |
| 8 | DEF | input | Output voltage scaling pin (low = nominal, high = nominal + 5%); internal ~400 kΩ pulldown resistor keeps logic low if floating. |
| 9 | SS/TR | input | Soft-start/tracking input; external capacitor sets internal voltage reference rise time for controlled startup and power sequencing applications. |
| 10 | AVIN | power_in | Analog supply voltage input for control circuitry, 3 V to 17 V range; must connect to same source as PVIN. |
| 11 | PVIN | power_in | Power supply voltage input for power stage, 3 V to 17 V range; must connect to same source as AVIN. |
| 12 | PVIN | power_in | Power supply voltage input for power stage, 3 V to 17 V range; must connect to same source as AVIN. |
| 13 | EN | input | Enable input (high = enabled, low = disabled and shutdown); internal ~400 kΩ pulldown resistor. |
| 14 | VOS | input | Output voltage sense pin; connection point for 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). |
