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 | power_out | Drain connection of the internal power N-channel FET (40V, 1.8A, 0.35Ω typical RDS(on)). Connect to the inductor and Schottky diode of the boost stage. Open LED protection monitors this node against the 37.5V typical OVP threshold. |+| 2 | GND | power_in | Device ground. Reference for all internal circuitry and the FB sense resistor return. Connect directly to the system ground plane with low impedance. |+| 3 | FB | input | Current feedback pin. Connect a current-sense resistor (RSET) from FB to GND to program LED current as ILED = VFB / RSET. Regulated to 204mV typical (188-220mV) at 100% CTRL duty; FB bias current ≤2.5µA. |+| 4 | CTRL | input | PWM dimming and enable input. Logic high threshold 1.2V (min), logic low 0.4V (max), with an internal ~300kΩ pull-down. Apply a 5-100kHz PWM signal (1%-100% duty) to modulate the effective FB reference (VFB = Duty × 204mV) for LED brightness dimming. Holding CTRL low for >2.5ms places the device in shutdown. |+| 5 | VIN | power_in | Supply input pin. Operating range 2.7V to 5.5V (7V absolute max). UVLO threshold ~2V (2.3V rising / 2.0V falling typical) with 200mV hysteresis. Quiescent current 0.3mA typical while switching; 1µA typical in shutdown. Bypass with a ≥1µF ceramic capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | LED Drivers |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `TPS61169DCKR`+- `TPS61169DCKRDCKT`++## CAD (KiCad official)++- Symbol: `TPS61169DCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (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/tps61169.pdf) (24 pp, sha256 `7d0b8ace2459a9fd`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
