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 | power_out | Switch pin of the power stage (datasheet lists its direction as I; typed here as power_out because it is the switching node driving the inductor). |+| 2 | SW | power_out | Switch pin of the power stage (datasheet lists its direction as I; typed here as power_out because it is the switching node driving the inductor). |+| 3 | FREQ | input | Selects switching frequency: FREQ low sets 2.8 MHz typical, FREQ high sets 1.4 MHz typical; it has a ~400 kΩ internal pull-down and can be left floating for 2.8 MHz operation. |+| 4 | PG | output | Open-drain power good output: high impedance when the output is in regulation and pulled low when below nominal; the pull-up resistor must not be connected to any voltage higher than the device input voltage. |+| 5 | FB | input | Feedback pin; for the fixed-output versions (this MPN is the 3.3 V version) connect it to GND for improved thermal performance, or leave it floating since it is internally connected with 400 kΩ to GND. |+| 6 | AGND | power_in | Analog ground; the exposed thermal pad is also connected to AGND. |+| 7 | CP | passive | Internal charge pump flying capacitor terminal; connect a 10 nF capacitor between CP and CN. |+| 8 | CN | passive | Internal charge pump flying capacitor terminal; connect a 10 nF capacitor between CP and CN. |+| 9 | SS | input | Soft-start control pin; a capacitor on this pin sets the soft-start time, and leaving it floating sets the minimum start-up time. |+| 10 | AVIN | power_in | Bias supply input voltage pin (device operates from 2.5 V to 6 V input range). |+| 11 | PVIN | power_in | Power supply input voltage pin (input voltage range 2.5 V to 6 V). |+| 12 | PVIN | power_in | Power supply input voltage pin (input voltage range 2.5 V to 6 V). |+| 13 | EN | input | Device enable: pull high to enable and pull low to disable; it has an internal ~400 kΩ pull-down. |+| 14 | PGND | power_in | Power ground connection. |+| 15 | PGND | power_in | Power ground connection. |+| 16 | VOS | input | Output voltage sense pin; it must be connected to the output voltage. |+| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | QFN-16-EP(3x3) |+| Category | Power Management (PMIC) |+| Pins | 17 |++## CAD (KiCad official)++- Symbol: `TPS62091RGTT`+- Footprint: `Package_DFN_QFN:QFN-16-1EP_3x3mm_P0.5mm_EP1.7x1.7mm`+- 3D model: QFN-16-EP(3x3) (KiCad packages3D, STEP)+- 3D model files: `tps62091rgtt-etched.step` / `tps62091rgtt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps62091rgtt.step` / `tps62091rgtt.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps62091) (29 pp, sha256 `0cf38963899420c5`, retrieved 2026-10-07, tier: lcsc)+- **Datasheet language:** Chinese.
