Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SS | input | Primary-side soft-start pin: an external capacitor to GND sets the rate at which the PWM duty cycle increases at startup, charged by a nominal 7-µA source, and the pin also serves as the AC ground return for the feedback pulse transformer. |+| 2 | FB | input | Control input for the differentiated start/stop pulses from the secondary-side PWM controller, which must have an amplitude of at least VSS ± 2.0 V for 25 ns to 200 ns per pulse and must not exceed VSS ± 7.0 V. |+| 3 | RT | input | A resistor from this pin to GND sets the free-running startup oscillator frequency, with RT specified from 22.2 kΩ to 133 kΩ for 360 kHz down to 60 kHz. |+| 4 | REF | output | The 5-V reference output supports external loads up to 10 mA and should be bypassed with at least 0.1 µF to GND. |+| 5 | CS | input | Pulse-by-pulse and shutdown overcurrent sense input: a level above the 1.0-V threshold terminates the pulse, and a signal above 1.375 V initiates a complete shutdown. |+| 6 | GND | power_in | Ground reference for all analog functions, which must be kept as clean as possible from switching noise and closely bypassed to VDD. |+| 7 | OUT | output | Drive pin for the external N-channel MOSFET power switch, sinking 1.5 A and sourcing 0.75 A, with a minimum of 4 Ω in series recommended to keep the driver within its safe operating area. |+| 8 | VDD | power_in | Power input for the control circuitry and MOSFET gate charge current, to be closely bypassed with at least 1.0 µF to GND, and internally clamped at 17.5 V so external current limiting is needed if the source can exceed this. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `UCC2960D`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `ucc2960d-etched.step` / `ucc2960d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc2960d.step` / `ucc2960d.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ucc2960) (14 pp, sha256 `b1e28c27a8a3f0c9`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
