UCC28880DR from Texas Instruments, in a SOIC-7. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground return. |
| 2 | GND | power_in | Device ground return (second GND pin, tie to pin 1). |
| 3 | FB | input | Feedback terminal. Senses the regulated output voltage via a resistor divider to close the control loop. |
| 4 | VDD | power_out | Supply pin for the internal low-voltage logic; supply is provided by an internal LDO. Requires an external bypass capacitor to GND. |
| 5 | HVIN | power_in | High-voltage supply pin (up to 700 V). Connects to the rectified mains and feeds the internal high-voltage current source used to generate VDD. |
| 6 | NC | unconnected | Not internally connected. Provides creepage/clearance between HVIN and FB. |
| 8 | DRAIN | power_in | Drain of the integrated 700-V power MOSFET switch. Connects to the switching node of the buck/buck-boost/flyback power stage. |
