UCC28700DBVR 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 | CBC | input | Cable compensation input pin programmed through resistor to GND for maximum 400 mV voltage compensation at 5-V output. |
| 2 | VDD | power_in | Bias supply input with 9 to 35 V operating range, 21 V UVLO turn-on threshold, 8.1 V turn-off threshold, requires bypass capacitor to GND. |
| 3 | DRV | output | Gate-drive output with 14-V clamp for external MOSFET switching transistor gate, providing 25-mA turn-on current source. |
| 4 | CS | input | Current-sense input with 0.75-V IPP(max) and 0.25-V IPP(min) thresholds, featuring 235-ns leading-edge blanking time. |
| 5 | GND | power_in | Ground reference pin for the controller and low-side return for gate-drive output. |
| 6 | VS | power_in | Voltage-sense input from auxiliary winding voltage divider providing output voltage feedback information sampled at demagnetization time. |
