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 | DELAY | passive | A resistor from DELAY to GND programs the nonoverlap delay between OUT1 and OUT2 (Delay1 and Delay2); absolute maximum 5.3V and 5mA. |+| 2 | LINE | input | Hysteretic comparator input with 5.0V on and 4.5V off thresholds, used to sense input line voltage and turn off OUT1 when the line is low. |+| 3 | VDD | power_in | Chip supply pin bypassed to PGND, with a 15V internal shunt clamp (10mA max) and UVLO of 9V on / 8.5V off for the -3 version; absolute maximum 16V. |+| 4 | OUT1 | output | Gate drive output for the main switch, capable of sourcing up to 0.5A and sinking 1A. |+| 5 | PGND | power_in | Ground connection for the gate drivers, connected to GND at a single point so no high frequency switching currents flow in the ground plane. |+| 6 | OUT2 | output | Gate drive output for the auxiliary switch with 0.3A drive current capability; inverted in the -3 version to drive NMOS FETs. |+| 7 | CLK | output | Oscillator clock output from a low impedance CMOS driver, high during guaranteed off time, able to synchronize up to five other UCC3580 PWMs. |+| 8 | GND | power_in | Signal ground. |+| 9 | RAMP | input | Feedforward ramp input where resistor R4 to input voltage and capacitor CR to GND set the ramp, with the flux comparator clamping volt-second product at 3.3V. |+| 10 | OSC2 | passive | Oscillator programming pin where a resistor to the timing capacitor controls the guaranteed off time. |+| 11 | OSC1 | passive | Oscillator programming pin where a resistor to the timing capacitor sets the maximum on time. |+| 12 | EAOUT | output | Error amplifier output and input to the PWM comparator, with loop compensation components connected from EAOUT to EAIN. |+| 13 | EAIN | input | Inverting input to the error amplifier whose noninverting input is internally set to 2.5V, used for feedback and loop compensation. |+| 14 | REF | power_out | Precision 5.0V reference output supplying up to 5mA to external circuits, bypassed to GND with a 1uF capacitor. |+| 15 | SS | passive | A capacitor from SS to ground programs the soft start time, charged by an internal 20uA current once startup conditions are met. |+| 16 | SHTDWN | input | Comparator input with a 0.5V threshold that stops the chip, holding OUT1 low while OUT2 continues to oscillate. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Power Management (PMIC) |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `UCC2580DTR-3`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)+- 3D model files: `ucc2580dtr-3-etched.step` / `ucc2580dtr-3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc2580dtr-3.step` / `ucc2580dtr-3.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/ucc3580-1) (16 pp, sha256 `22578373a5379f7a`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-sonnet-5-5` (text+vision), consensus `claude-opus-5-5` (agreed), guards: pin_guards 0.1: passed.
