UCC3808DTR-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 | Output of the error amplifier and input of the PWM comparator with 2MHz typical gain bandwidth product. |
| 2 | FB | input | Inverting input to the error amplifier; minimize lead length and stray capacitance for best stability. |
| 3 | CS | input | Input to the PWM, peak current, and overcurrent comparators with typical overcurrent threshold of 0.75V. |
| 4 | RC | input | Oscillator programming pin; connect 10kΩ to 200kΩ resistor to VDD and 100pF to 1000pF capacitor to GND. |
| 5 | GND | power_in | Reference ground and power ground for all functions; requires low-impedance PCB ground plane. |
| 6 | OUTB | output | Alternating high current output stage capable of 500mA peak source current and 1A peak sink current. |
| 7 | OUTA | output | Alternating high current output stage capable of 500mA peak source current and 1A peak sink current. |
| 8 | VDD | power_in | Power input connection with supply voltage range 5V to 14V for UCC3808-2; bypass to GND with 1μF ceramic capacitor. |
