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 | TOFF | passive | Switching-frequency setting pin. An external capacitor connected to this pin sets the switching (off-time) frequency; recommended operating frequency is below 500 kHz. |+| 2 | VDD | power_in | Chip supply rail, internally clamped by a shunt regulator to typically 5.5 V. Fed from VIN through an external series resistor (RVDD); the internal Zener clamp current must be kept below 10 mA. UVLO turn-on at 3.2 V rising, turn-off at 2.7 V falling. |+| 3 | GND | power_in | Device ground reference for all internal circuitry and the sensing amplifiers. |+| 4 | EN | input | Chip enable; active-high. Logic high (>= 0.4 x VDD) enables the controller, logic low (<= 0.8 V) puts the part into standby (I_INQ ~200 uA). May be driven with a PWM signal for LED dimming. |+| 5 | COMP | passive | Loop / frequency compensation node for the internal error amplifier. Connect an external capacitor (typically 200 pF to 1 nF) to GND; larger values reduce loop bandwidth. |+| 6 | CS | input | Output LED current sense input. The regulation loop holds this pin at a nominal 250 mV (240-260 mV) across the sense resistor RCS, so ILED = 0.25 V / RCS. |+| 7 | DRV | output | Gate-drive output for the external power MOSFET. Nominal drive swing tracks VDD (~5.5 V); rise/fall times ~50 ns into 1 nF. Choose a MOSFET whose RDS(on) is fully enhanced at VGS = 5.5 V. |+| 8 | ILIM | input | Power-MOSFET peak-current limit sense input. Sets the cycle-by-cycle inductor peak-current limit via an external sense resistor RILIM, where ILIMIT = 0.25 V / RILIM. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XDS |+| Package | SOIC-8 |+| Category | LED-drv |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `TX6301`+- 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:** [XDS datasheet](docs/tx6301-datasheet.pdf) (8 pp, sha256 `aade119490c082a5`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
