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 | SW | output | Switch pin of the power stage. Connect to the external inductor. Absolute maximum voltage range -0.3 V to VIN + 0.3 V. Pins 1 and 2 are tied together internally to the switching node. |+| 2 | SW | output | Switch pin of the power stage. Connect to the external inductor. Absolute maximum voltage range -0.3 V to VIN + 0.3 V. Pins 1 and 2 are tied together internally to the switching node. |+| 3 | FREQ | input | Switching frequency select. FREQ = Low sets typical switching frequency to 2.8 MHz; FREQ = High sets it to 1.4 MHz. Has an internal ~400 kOhm pull-down resistor and can be left floating for 2.8 MHz operation. |+| 4 | PG | output | Power good open-drain output. High impedance when output voltage is within regulation, pulled low when output is below nominal. Pull-up resistor must not be tied to a voltage higher than VIN. Sink current up to 1 mA. |+| 5 | FB | input | Feedback pin. For adjustable version, connect a resistor divider from output to set VOUT (VFB = 0.8 V typ). For fixed-output versions may be tied to GND for improved thermal performance; has ~400 kOhm pull-down active when EN is low. |+| 6 | AGND | power_in | Analog ground reference for the control circuitry. Must be connected to the exposed thermal pad and to PGND on the PCB. |+| 7 | CP | passive | Internal charge-pump flying capacitor terminal. Connect a 10 nF capacitor between CP and CN. Absolute max -0.3 V to VIN + 7.0 V. |+| 8 | CN | passive | Internal charge-pump flying capacitor terminal. Connect a 10 nF capacitor between CP and CN. Absolute max -0.3 V to VIN + 7.0 V. |+| 9 | SS | input | Softstart control pin. A capacitor to GND sets the softstart time using the ~7.5 uA softstart current. Leaving it floating uses the minimum start-up time. Also used for output voltage tracking. |+| 10 | AVIN | power_in | Bias supply input voltage pin for the internal analog circuitry. Recommended input range 2.5 V to 6 V; absolute max 7 V. Typically tied to PVIN with local decoupling. |+| 11 | PVIN | power_in | Power supply input voltage pin for the power stage. Recommended input range 2.5 V to 6 V; absolute max 7 V. Pins 11 and 12 must be tied together and bypassed with a low-ESR ceramic capacitor (typ. 10 uF). |+| 12 | PVIN | power_in | Power supply input voltage pin for the power stage. Recommended input range 2.5 V to 6 V; absolute max 7 V. Pins 11 and 12 must be tied together and bypassed with a low-ESR ceramic capacitor (typ. 10 uF). |+| 13 | EN | input | Device enable. Pull high to enable; pull low to disable. Has an internal ~400 kOhm pull-down resistor active when EN is low. VIH >= 1 V, VIL <= 0.4 V. |+| 14 | PGND | power_in | Power ground return for the power stage. Pins 14 and 15 must be tied together and connected to the exposed thermal pad and system ground plane. |+| 15 | PGND | power_in | Power ground return for the power stage. Pins 14 and 15 must be tied together and connected to the exposed thermal pad and system ground plane. |+| 16 | VOS | input | Output voltage sense pin. Must be connected directly to the regulated output voltage node (VOUT) at the load side of the output capacitor. |+| 17 | EP | power_in | Exposed thermal pad, internally connected to AGND. Must be soldered to the PCB ground plane for electrical connection and thermal reliability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-16-EP(3x3) |+| Category | Power Management (PMIC) |+| Pins | 17 |++## Ordering variants++Same part, different packaging or reel option.++- `TPS62090RGTR`+- `TPS62090RGTRRGTT`++## CAD (KiCad official)++- Symbol: `TPS62090RGTR`+- Footprint: `Package_DFN_QFN:QFN-16-1EP_3x3mm_P0.5mm_EP1.7x1.7mm`+- 3D model: VQFN-16-EP(3x3) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps62090.pdf) (32 pp, sha256 `1aca00440b3d4033`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
