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 | GND | power_in | Ground pin. Common return for the input capacitor, output capacitor, and internal control circuitry. |+| 2 | SW | output | Switch node connected to the internal high-side and low-side FETs and the inductor terminal. Connect the output filter inductor (typ. 1.0 µH) between SW and VOUT. Absolute max -0.3 V to VIN+0.3 V DC; -3 V to 10 V transient <10 ns. |+| 3 | VIN | power_in | Input supply voltage pin, 2.5 V to 5.5 V. Place the input capacitor as close as possible between VIN and GND. Absolute max 6.5 V. |+| 4 | EN | input | Device enable logic input. Logic high (>1.2 V rising) enables the converter; logic low (<0.4 V falling) forces shutdown (≤2 µA IQ). Do not leave floating. Absolute max 6.5 V. |+| 5 | FB | input | Feedback pin for the internal control loop. Connect this pin to the center tap of an external resistor divider from VOUT to set the output voltage. Internal reference VFB = 600 mV (±1% at 0-125°C). |+| 6 | PG | output | Power-good open-drain output pin. Requires an external pullup resistor tied to a rail no higher than 5.5 V (do NOT tie to a rail higher than 5.5 V even if VIN is higher). Asserts high when FB is within ~96% of nominal; leave open or tie to GND if unused. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-563 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `TPS62A02DRLR`+- `TPS62A02DRLRADRLR`+- `TPS62A02DRLRNDRLR`+- `TPS62A02DRLRNADRLR`+- `TPS62A02DRLRDDCR`+- `TPS62A02DRLRAPDDCR`+- `TPS62A02DRLRPDDCR`++## CAD (KiCad official)++- Symbol: `TPS62A02DRLR`+- Footprint: `Package_TO_SOT_SMD:SOT-563`+- 3D model: SOT-563 (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/tps62a02.pdf) (31 pp, sha256 `cad0b23ab8636891`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
