UCC28056DBVR

Texas Instruments · AC-DC Controllers And Regulators · SOT-23-6

UCC28056DBVR from Texas Instruments, in a SOT-23-6. 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; over-voltage protection halts switching if voltage exceeds VOvp1Rise and resumes when voltage drops below VOvp1Fall.
2 ZCD/CS input Zero-crossing detection and current sense input; monitors current sense resistor voltage when DRV is high and drain voltage waveform when DRV is low, enables over-current protection, valley synchronization, and second-level output over-voltage protection.
3 VCC power_in Positive supply voltage input; switching starts when VCC exceeds VCCStart and stops when VCC drops below VCCStop for longer than TUVLOBlk.
4 GND power_in Controller ground reference; connect to power stage at the lower terminal of current sense resistor RCS only.
5 DRV bidirectional Gate drive output with internal voltage limit VDRHigh; external resistor from DRV to GND adjusts delay between drain voltage falling and DRV rising edge for valley-synchronized turn-on.
6 COMP bidirectional Error amplifier output and power demand input with internal voltage limit VCOClmp, internally discharged in stop or over-voltage states, with switching control via VBSTFall and VBSTRise thresholds.
