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 | RTDEL | input | A resistor from this pin to GND programs the turn-on delay of the two gate drive outputs to accommodate the resonant transitions of the active clamp power converter. |+| 2 | RTON | input | A resistor from this pin to GND programs an internal current source that charges the internal timing capacitor. |+| 3 | RTOFF | input | A resistor from this pin to GND programs an internal current source that discharges the internal timing capacitor. |+| 4 | VREF | power_in | This 5-V reference can supply an external load of up to 5 mA and should be bypassed to AGND as close as possible to the device. |+| 5 | SYNC | input | This unidirectional input synchronizes the internal oscillator, and the synchronizing frequency must be higher than the free-running frequency, with a minimum pulse width of approximately 50 ns. |+| 6 | GND | power_in | This pin is the fundamental analog ground for the PWM control circuitry and should be connected directly to PGND at the device. |+| 7 | CS | input | This pin senses peak current for current-mode control and current limiting, with pulse-by-pulse current limiting activating at approximately 1.27 V for the UCC2892. |+| 8 | RSLOPE | input | A resistor from this pin to GND sets the amplitude of the internal slope compensation current. |+| 9 | FB | input | This pin receives the control voltage from an external optocoupler or error amplifier to set the PWM duty cycle. |+| 10 | SS/SD | input | A capacitor from this pin to GND programs the soft-start interval, is charged by an internal current source of IRTON, and is discharged by a current source equal to IRTON during a fault. |+| 11 | PGND | power_in | This pin is the current return for the high-current output drivers OUT and AUX and should be kept as short as possible on the switching current path. |+| 12 | AUX | output | This output drives the auxiliary clamp MOSFET, turning it on when the main switch turns off, with 2-A source turn-on current and 2-A sink turn-off current. |+| 13 | OUT | output | This output drives the main N-channel MOSFET with 2-A source turn-on current and 2-A sink turn-off current, and a 10-kΩ resistor to PGND is recommended. |+| 14 | VDD | power_in | This is the power supply for the device, which requires a 1-µF capacitor from VDD to PGND with a value at least 10 times greater than the capacitor on VREF. |+| 15 | LINEUV | input | This pin enables and disables the converter by monitoring the bulk input voltage against a 1.27-V threshold, with hysteresis set by an internal current source. |+| 16 | LINEOV | input | For the UCC2892, this pin provides the line overvoltage function, scaling the input voltage to a precise 1.27-V threshold with user-programmable hysteresis. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Power Management (PMIC) |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `UCC2892PW`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)+- 3D model files: `ucc2892pw-etched.step` / `ucc2892pw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc2892pw.step` / `ucc2892pw.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/ucc2892.pdf) (41 pp, sha256 `0b123b68deef52c5`, 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.
