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 | OUTB | output | Alternating high-current push-pull output stage rated for 500 mA peak source and 1 A peak sink to drive a power MOSFET gate, with about 110 ns dead time against OUTA. |+| 2 | GND | power_in | Reference ground and power ground for all functions, and a low-impedance circuit board ground plane is highly recommended due to high currents and high-frequency operation. |+| 3 | RT | input | Oscillator programming pin: a timing resistor from RT to GND sets fOSC, with a recommended resistor range of 25 kΩ to 698 kΩ and a nominal RT voltage of 1.5 V (1.2 V to 1.6 V). |+| 4 | CS | input | Current-sense input to the PWM comparator, cycle-by-cycle current limit and overcurrent comparator, where exceeding the 0.75 V typical overcurrent threshold causes a soft-start cycle, and the absolute maximum is −0.3 V to VDD + 0.3 V and not more than 6 V. |+| 5 | ISET | input | Current selection for slope compensation, where a resistor RSET from ISET to ground sets the ramp so that IRAMP peak = 5 × ISET peak. |+| 6 | CTRL | input | Error voltage input to the PWM comparator, with an internal divider ratio of 0.45 and an absolute maximum range of −0.3 V to VDD + 0.3 V. |+| 7 | VDD | power_in | Power input connection with an absolute maximum of 15 V at IDD < 10 mA, requiring a 1 µF decoupling capacitor to GND as close to the chip as possible. |+| 8 | OUTA | output | Alternating high-current push-pull output stage rated for 500 mA peak source and 1 A peak sink to drive a power MOSFET gate, switching at half the oscillator frequency. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `UCC28083PW`+- Footprint: `Package_SO:TSSOP-8_3x3mm_P0.65mm`+- 3D model: TSSOP-8 (KiCad packages3D, STEP)+- 3D model files: `ucc28083pw-etched.step` / `ucc28083pw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc28083pw.step` / `ucc28083pw.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/lit/ds/symlink/ucc28083.pdf) (28 pp, sha256 `19bab60962d5c6f5`, retrieved 2026-10-08, tier: manufacturer)+- **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.
