UCC28056DBVT

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

UCC28056DBVT 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 with internal output over-voltage protection; switching halts if voltage exceeds VOvp1Rise and resumes below VOvp1Fall.
2 ZCD/CS input Zero-crossing detector and current sense input fed by Drain-Source voltage divider; monitors current sense resistor when DRV high for over-current protection and Drain waveform when DRV low for valley detection and second-level over-voltage protection.
3 VCC power_in Positive supply voltage input with operating range from VCCStart to VCCStop; switching starts above VCCStart and stops below VCCStop for duration exceeding TUVLOBlk.
4 GND power_in Ground reference pin connected to power stage at lower terminal of current sense resistor RCS only.
5 DRV output Gate driver output internally limited to VDRHigh that drives the main power MOSFET with external resistor adjustable turn-on delay aligned to valley minimum.
6 COMP bidirectional Error amplifier output internally limited to VCOClmp for voltage loop compensation with internal discharge resistor RCODisch; switching stops when voltage drops below VBSTFall and resumes above VBSTRise.
