UCC2808D-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; the error amplifier is internally current limited so zero duty cycle can be forced by pulling COMP to GND, and soft-start clamps the maximum COMP voltage. |
| 2 | FB | input | Inverting input to the error amplifier, with the lead length and stray capacitance kept small for best stability; analog input limit is -0.3 V to VDD + 0.3 V. |
| 3 | CS | input | Input to the PWM, peak current, and overcurrent comparators, where exceeding the 0.7 V to 0.8 V overcurrent threshold causes a soft-start cycle; analog input limit is -0.3 V to VDD + 0.3 V. |
| 4 | RC | input | Oscillator programming pin, with a timing resistor between 10 kΩ and 200 kΩ (avoid resistors below 10 kΩ) and a timing capacitor between 100 pF and 1000 pF. |
| 5 | GND | power_in | Reference ground and power ground for all functions, which should be connected to a low-impedance ground plane. |
| 6 | OUTB | output | Alternating high current output stage, capable of 500 mA peak source current and 1 A peak sink current, switching at half the oscillator frequency in push-pull with OUTA. |
| 7 | OUTA | output | Alternating high current output stage, capable of 500 mA peak source current and 1 A peak sink current, switching at half the oscillator frequency in push-pull with OUTB. |
| 8 | VDD | power_in | Power input for the device; the recommended supply for the UCCx808-2 is 5 V to 14 V, with an absolute maximum of 15 V at IDD of 10 mA or less, and a 1 µF decoupling capacitor is recommended. |
