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 | BOOT | passive | Boost capacitor pin for the high-side FET gate driver. Connect a 0.01µF low-ESR ceramic capacitor from BOOT to PH to provide gate drive above VIN. |+| 2 | NC | unconnected | Not connected internally. |+| 3 | NC | unconnected | Not connected internally. |+| 4 | VSENSE | input | Feedback voltage input for the regulator error amplifier. Connect to the output voltage divider; regulates to VFB = 1.221V typical (adjustable output down to 1.22V). |+| 5 | ENA | input | Active-high enable / on-off control. Below 0.5V the device stops switching; above 1.3V the device starts switching. Internally pulled up via a 1.5MΩ resistor so the pin may be left floating; do not connect through a resistor to ground. |+| 6 | GND | power_in | Device ground return. |+| 7 | VIN | power_in | Input supply voltage, 5.5V to 36V (40V absolute max). Bypass with a high-quality low-ESR ceramic capacitor placed within 1mm of VIN and GND. |+| 8 | PH | power_out | Phase / switch node - source of the high-side power MOSFET. Connect to the external inductor and catch (Schottky) diode. Delivers up to 2A continuous (3A peak); on-resistance 110mΩ typical. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `TPS5420DRDR`+- `TPS5420DRD`++## CAD (KiCad official)++- Symbol: `TPS5420DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (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/tps5420.pdf) (35 pp, sha256 `cd667e69b40fa9c0`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
