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 | CTRL | input | Error voltage input to the PWM comparator, typically driven from a secondary-side error amplifier through an opto-coupler, with an internal divider ratio of 0.45 to keep a usable range at the minimum VDD of 4.1 V. |+| 2 | ISET | input | Current selection for slope compensation: a resistor RSET from ISET to ground sets the ramp, with the ISET pin voltage tracking the 1.5 V internal oscillator ramp and ISLOPE = 5 × ISET. |+| 3 | CS | input | Current-sense input to the PWM comparator, cycle-by-cycle peak current comparator and overcurrent comparator; exceeding the overcurrent threshold (0.70 V to 0.80 V) causes a soft-start cycle, and the absolute maximum is VDD + 0.3 V and not more than 6 V. |+| 4 | RT | input | Oscillator programming pin: an external resistor from RT to GND sets the oscillator frequency, with nominal RT voltage of 1.5 V (1.2 V to 1.6 V) and a recommended timing resistor range of 25 kΩ to 698 kΩ. |+| 5 | GND | power_in | Reference ground and power ground for all functions; due to high currents and high-frequency operation, a low-impedance circuit board ground plane is highly recommended. |+| 6 | OUTB | output | High-current push-pull output stage, alternating with OUTA, capable of 500 mA peak source and 1 A peak sink to drive a power MOSFET gate. |+| 7 | OUTA | output | High-current push-pull output stage, alternating with OUTB, capable of 500 mA peak source and 1 A peak sink to drive a power MOSFET gate. |+| 8 | VDD | power_in | Power input connection with absolute maximum supply voltage of 15 V (IDD < 10 mA); a 1-µF ceramic decoupling capacitor to GND placed close to the chip is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `UCC28086DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `ucc28086dr-etched.step` / `ucc28086dr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc28086dr.step` / `ucc28086dr.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/ucc28086.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.
