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 | VOSNS | input | Voltage error amplifier inverting input, regulated against the internal VOSReg reference of 2.45-2.55 V (2.5 V typical), which also provides first-level output overvoltage protection: switching is suspended when VOSNS rises above VOvp1Rise (2.69-2.81 V) and resumes when it falls below VOvp1Fall (2.60-2.73 V) at VCC = 12 V. |+| 2 | ZCD/CS | input | Input fed by a resistor divider across the power MOSFET drain and source that senses the current-sense voltage while DRV is high (overcurrent thresholds 0.5 V for Ocp1 and 0.75 V for Ocp2) and the drain waveform while DRV is low (zero-current detection, line feedforward, line undervoltage, and second-level output overvoltage at 1.125 V), with absolute maximum rating -0.5 to 7 V. |+| 3 | VCC | power_in | Positive supply pin: switching starts once VCC exceeds VCCStart and stops if VCC stays below VCCStop for longer than TUVLOBlk, with the device to be supplied from 11 V to 34 V and an absolute maximum of 36 V. |+| 4 | GND | power_in | Controller ground reference, to be connected only to the terminal of the current-sense resistor RCS on the power-stage side, so that the ZCD/CS-to-GND voltage equals the RCS voltage during MOSFET conduction. |+| 5 | DRV | bidirectional | Gate drive output for the main power MOSFET, internally limited to VDRHigh (10-15 V, 13.7 V typical at VCC = 25 V) with a peak sink current of 1 A and peak source current of -0.7 A, where an external resistor from DRV to GND selects the valley-switching delay TZCDR during startup and absolute maximum is -0.3 to 20 V. |+| 6 | COMP | bidirectional | Internal transconductance error amplifier output and power-demand input, where the voltage-loop compensation RC network connects from this pin to GND, the pin is internally clamped to 5.5-5.71 V high, switching turns off below VBSTFall (0.5 V) and back on above VBSTRise (0.625 V) for burst mode, and the absolute maximum rating is -0.5 to 7 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `UCC28056ADBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)+- 3D model files: `ucc28056adbvr-etched.step` / `ucc28056adbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc28056adbvr.step` / `ucc28056adbvr.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/ucc28056) (49 pp, sha256 `c9fa6ad1b816408d`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
