TPS54335ADRCR from Texas Instruments, in a VSON-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | 4.5-V to 28-V input supply voltage pin. Powers the internal high-side MOSFET drain and the device bias. |
| 2 | PH | output | Switch node - the source of the internal high-side power MOSFET and drain of the low-side MOSFET. Connects to the external inductor and bootstrap capacitor return. |
| 3 | GND | power_in | Device ground. Tie all GND pins and the exposed thermal pad to the PCB ground plane. |
| 4 | GND | power_in | Device ground. Tie all GND pins and the exposed thermal pad to the PCB ground plane. |
| 5 | GND | power_in | Device ground. Tie all GND pins and the exposed thermal pad to the PCB ground plane. |
| 6 | VSENSE | input | Inverting input of the transconductance (gm) error amplifier. Connect the feedback resistor divider from VOUT here; regulates to the 0.8-V internal reference. |
| 7 | COMP | output | Error-amplifier output and input to the output switch-current comparator. Connect the frequency-compensation network (RC/RCC) between COMP and GND. |
| 8 | EN | input | Enable pin. Float to enable the device (internal pull-up); drive low to disable. Rising threshold 1.21 V typ, falling 1.17 V typ. Absolute max 6 V. |
| 9 | BOOT | passive | Bootstrap capacitor pin for the high-side MOSFET gate driver. Connect a capacitor (typ 0.1 µF) between BOOT and PH. When the BOOT-PH voltage falls below the UVLO (~2.1 V), the high-side is forced off to refresh the capacitor. |
| 10 | RT | passive | Switching-frequency programming pin (TPS54335A / TPS54335-1A variant). Connect an external resistor from RT to GND to set the switching frequency between 50 kHz and 1.5 MHz (e.g. R_RT = 100 kΩ → ~480 kHz; 30 kΩ → ~1.5 MHz). |
| PAD | Thermal Pad | power_in | Exposed thermal pad on the underside of the VSON package. Must be connected to the PCB ground plane with multiple thermal vias for proper thermal performance; also serves as the primary electrical ground return. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 633 faces against 74 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
