TPS62133AQRGTTQ1 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 the internal MOSFET switches; the inductor connects between SW and the output capacitor, with DC voltage limited to VIN+0.3 V and AC (less than 10 ns) limited to -2 V to 24.5 V. |
| 2 | SW | output | Switch node connected to the internal MOSFET switches; the inductor connects between SW and the output capacitor, with DC voltage limited to VIN+0.3 V and AC (less than 10 ns) limited to -2 V to 24.5 V. |
| 3 | SW | output | Switch node connected to the internal MOSFET switches; the inductor connects between SW and the output capacitor, with DC voltage limited to VIN+0.3 V and AC (less than 10 ns) limited to -2 V to 24.5 V. |
| 4 | PG | output | Open-drain power-good output (High = VOUT ready, Low = VOUT below nominal regulation) that requires a pull-up resistor, with a maximum sink current of 10 mA and pin voltage limited to -0.3 V to 7 V. |
| 5 | FB | input | Voltage feedback input for the adjustable version, where a resistive divider connects to this pin; the datasheet recommends connecting FB to AGND on fixed-output versions for improved thermal performance, with pin voltage limited to 7 V. |
| 6 | AGND | power_in | Analog ground that must be connected directly to the exposed thermal pad and the common ground plane. |
| 7 | FSW | input | Switching frequency select, Low = 2.5 MHz and High = 1.25 MHz for typical operation; an internal pull-down keeps the pin low if it is floating, with pin voltage limited to 7 V. |
| 8 | DEF | input | Output voltage scaling input, Low = nominal output voltage and High = nominal output voltage + 5%; an internal pull-down keeps the pin low if it is floating, with pin voltage limited to 7 V. |
| 9 | SS/TR | input | Soft-start and tracking pin; an external capacitor on this pin sets the internal reference rise time and it can be used for tracking and sequencing, with pin voltage limited to VIN+0.3 V. |
| 10 | AVIN | power_in | Supply voltage for the control circuitry, to be connected to the same source as PVIN; recommended VIN range is 3 V to 17 V with an absolute maximum of 20 V. |
| 11 | PVIN | power_in | Supply voltage for the power stage, to be connected to the same source as AVIN; recommended VIN range is 3 V to 17 V with an absolute maximum of 20 V. |
| 12 | PVIN | power_in | Supply voltage for the power stage, to be connected to the same source as AVIN; recommended VIN range is 3 V to 17 V with an absolute maximum of 20 V. |
| 13 | EN | input | Enable input (High = enabled, Low = disabled); an internal pull-down keeps the pin low if it is floating, with pin voltage limited to VIN+0.3 V. |
| 14 | VOS | input | Output voltage sense pin and connection for the control loop circuitry, with pin voltage limited to 7 V. |
| 15 | PGND | power_in | Power ground that must be connected directly to the exposed thermal pad and the common ground plane. |
| 16 | PGND | power_in | Power ground that must be connected directly to the exposed thermal pad and the common ground plane. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
