It steps a 3 to 5.5 V input up to as much as 38 V to push current through several LEDs in series, holding the current constant so brightness stays even, and a single CTRL pin dims the string either by a simple PWM or by TI's EasyScale one-wire digital protocol. External FB and COMP set the current and loop. A compact backlight and indicator-string driver.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VIN | power_in | Input supply pin for the IC. Connect to a 3-V to 18-V supply with a ≥ 1 µF bypass capacitor. UVLO rising ~2.5 V with 70 mV hysteresis. |+| 2 | CTRL | input | Multifunction control pin for enable, one-wire EasyScale digital dimming, and PWM dimming (5 kHz-100 kHz). Logic high ≥ 1.2 V, logic low ≤ 0.4 V; internal 800-kΩ pull-down. Holding low > 2.5 ms shuts the device down. |+| 3 | SW | power_out | Switching node of the internal 40-V N-channel MOSFET (RDS(on) = 0.3 Ω typ, ILIM = 1.2 A). Connect the switched side of the boost inductor here; also senses output voltage for 38-V open-LED protection. |+| 4 | GND | power_in | Device ground return. Also the reference for the thermal pad, which should be soldered to the analog ground plane. |+| 5 | COMP | output | Output of the transconductance error amplifier. Connect an external capacitor (e.g. 220 nF) to compensate the loop; Gea = 320 umho typ, Rea = 6 MΩ. |+| 6 | FB | input | Feedback pin for LED current sensing. Connect the sense resistor (Rset) from FB to GND; regulated feedback voltage is 200 mV (typ, 2% accuracy). |++## Key specifications++| Parameter | Value |+|---|---|+| Type | White-LED boost driver (constant current) |+| Input | 3-5.5 V |+| Output | Up to 38 V (LED string) |+| Dimming | PWM or EasyScale 1-wire (CTRL) |+| Switch | Integrated |+| Current set | External (FB) |+| Package | SOT-23-6 |++## Ordering variants++- `TPS61165DBVR (SOT-23-6)`+- `TPS61165DBVT (SOT-23-6, small reel)`++## CAD (KiCad official)++- Symbol: `Driver_LED:TPS61165DBV (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (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/tps61165.pdf) (38 pp, sha256 `d3515134b3388868`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
