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 | VCC | power_out | Internal regulator output, typically regulated to 5.4 V. Connect a capacitor larger than 1 µF between VCC and GND. |+| 2 | PGND | power_in | Power Ground. Must be connected to the GND pin for normal operation. The PGND and GND pins are not internally shorted. |+| 3 | IADJ | input | Average LED current setting. An external resistor R_IADJ connecting IADJ to ground programs the average LED current. IADJ pin voltage is typically 1.25 V. |+| 4 | GND | power_in | Analog Signal Ground. |+| 5 | FS | input | Switching frequency setting. An external resistor R_FS connecting FS to ground programs the switching frequency from 50 kHz to 500 kHz (e.g. 500 kHz typical at R_FS = 20 kΩ). |+| 6 | DIM | input | PWM Dimming Control. Apply a logic-level PWM signal to dim the LED string. Internally pulled up. Upper threshold typ 1.0 V, lower threshold typ 0.44 V. |+| 7 | LX | output | Integrated MOSFET drain. Internally connected to the drain of the integrated low-side N-channel MOSFET. Connect to the output inductor and anode of the Schottky diode. R_DS(on) typ 1.4 Ω. |+| 8 | VIN | power_in | Input voltage supply pin to the device. Input voltage range 4.5 V to 65 V (67 V transient). |+| 9 | Thermal Pad | power_in | Thermal connection pad. Connect to a ground plane for heat dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SO-8-EP |+| Category | LED-drv |+| Pins | 9 |++## Ordering variants++- `TPS92511DDARDDAR`++## CAD (KiCad official)++- Symbol: `TPS92511DDAR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8-EP (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/tps92511ddar.pdf) (31 pp, sha256 `d5e24ca64833ee45`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
