TPS62142RGTT from Texas Instruments, in a QFN-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 | Output power good indicator; high when VOUT ready, low when VOUT below nominal regulation; open-drain output requiring pull-up resistor. |
| 5 | FB | input | Voltage feedback input for adjustable version; recommended to connect to AGND on fixed output versions (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. |
| 8 | DEF | input | Output voltage scaling input; low = nominal voltage, high = nominal voltage + 5%. |
| 9 | SS/TR | input | Soft-start/tracking input; external capacitor sets internal voltage reference rise time for tracking and sequencing. |
| 10 | AVIN | power_in | Supply voltage input for control circuitry; must be connected to same source as PVIN. |
| 11 | PVIN | power_in | Supply voltage input for power stage; must be connected to same source as AVIN. |
| 12 | PVIN | power_in | Supply voltage input for power stage; must be connected to same source as AVIN. |
| 13 | EN | input | Enable input; high = device enabled, low = device disabled/shutdown. |
| 14 | VOS | input | Output voltage sense pin for control loop circuitry connection. |
| 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). |
