UCC2808DTR-1

Texas Instruments · AC-DC Controllers And Regulators · SOIC-8

UCC2808DTR-1 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 error amplifier and input of PWM comparator; soft-start internally clamps maximum voltage.
2 FB input Inverting input to error amplifier; rated -0.3V to VDD+0.3V (max 6V); minimize lead length and stray capacitance.
3 CS input Current sense input to PWM, peak current, and overcurrent comparators; rated -0.3V to VDD+0.3V (max 6V).
4 RC input Oscillator programming pin; external RC network sets frequency (recommended RT 10-200kΩ, CT 100-1000pF).
5 GND power_in Reference and power ground for all functions; low-impedance PCB ground plane required.
6 OUTB output Alternating high-current output stage; 500mA peak source current, 1A peak sink current, operates at half oscillator frequency.
7 OUTA output Alternating high-current output stage; 500mA peak source current, 1A peak sink current, operates at half oscillator frequency.
8 VDD power_in Power supply input; 13-14V operating range for UCC2808-1 variant, 130-260µA startup current, 1-2mA operating current.
