UCC2808DTR-2 from Texas Instruments, in a SOIC-8. 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 | COMP | bidirectional | Error amplifier output and PWM comparator input; sources 0.25-0.5mA or sinks 0.3-2.5mA with internal current limiting and soft-start clamping. |
| 2 | FB | input | Inverting input to error amplifier; accepts analog feedback from -0.3V to VDD+0.3V (6V max). |
| 3 | CS | input | Current sense input to PWM and overcurrent comparators; accepts -0.3V to VDD+0.3V with 0.75V typical overcurrent threshold. |
| 4 | RC | input | Oscillator programming pin; connect 10kΩ-200kΩ resistor to VDD and 100pF-1000pF capacitor to GND for frequency setting. |
| 5 | GND | power_in | Reference and power ground for all functions; low-impedance PCB ground plane recommended. |
| 6 | OUTB | output | Alternating push-pull output stage; 500mA peak source, 1A peak sink, 25-60ns rise/fall time at 1nF load. |
| 7 | OUTA | output | Alternating push-pull output stage; 500mA peak source, 1A peak sink, 25-60ns rise/fall time at 1nF load. |
| 8 | VDD | power_in | Power supply input; 5-14V operating range for UCCx808-2 with internal 13-15V zener clamp. |
