UCC28056CDBVR 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 | Output voltage sense input to error amplifier inverting input with internal reference VOSReg = 2.5V; output overvoltage protection triggers at VOvp1Rise = 2.75V and recovers at VOvp1Fall = 2.675V. |
| 2 | ZCD/CS | input | Zero-current detection and current sense input monitoring drain-source voltage and current; primary overcurrent protection threshold VZCOcp1 = 0.5V, secondary VZCOcp2 = 0.75V, line undervoltage threshold VZCBoRise = 0.3V. |
| 3 | VCC | power_in | Positive supply voltage with startup enable threshold VCCStart = 11V, dropout threshold VCCStop = 8.85V, operating range 8.5V to 34V. |
| 4 | GND | power_in | Ground reference for controller connected only to power stage ground below current sense resistor RCS terminal. |
| 5 | DRV | output | Gate driver output for main power MOSFET with output low VDRLow = 0.9V and high voltage limited to VDRHigh = 13.7V; external RDG resistor programs valley-switch delay TZCDR through eight discrete levels. |
| 6 | COMP | output | Error amplifier output with internal clamping to maximum VCOClmp = 5.6V and minimum VCOSat = 0V; internal discharge resistor RCODisch operates during Stopb state or Ovp2 comparator trip for fault protection. |
