UCC28700DBVT 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 programming pin (−0.5 to 5 V) connected to external resistor for output voltage rise adjustment across load current range. |
| 2 | VDD | power_in | Bias supply voltage input (9-35 V operating range) requiring bypass capacitor to GND; UVLO on/off thresholds at 21 V and 8.1 V. |
| 3 | DRV | output | Gate-drive output clamped to 14-16 V with 25 mA source current for MOSFET gate control through external series resistor. |
| 4 | CS | input | Current-sense input (0.25-0.75 V normal operating range) with 235 ns leading-edge blanking for peak primary current monitoring. |
| 5 | GND | power_in | Ground reference for controller and low-side return for DRV output; bypass and AC decoupling capacitors should connect close to this pin. |
| 6 | VS | power_in | Voltage-sense input from auxiliary-winding voltage divider for primary-side output voltage feedback; 4.05 V internal regulating level. |
