UCC2803QDRQ1

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

UCC2803QDRQ1 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 output Error amplifier output and PWM comparator input with 2MHz bandwidth and internal current limiting.
2 FB input Inverting input of error amplifier; maintain short lead length and minimal stray capacitance.
3 CS input Current sensing input with 100ns digital leading edge blanking after OUT rising edge.
4 RC input Oscillator timing pin; external RC network sets switching frequency and maximum duty cycle.
5 GND power_in Ground and power return reference for all device functions.
6 OUT output High current power driver output capable of ±750mA peak current; actively held low when VCC below threshold.
7 VCC power_in Power supply input requiring current limiting resistor; typical operating range 11V to 12V per UVLO thresholds.
8 REF output Voltage reference output (4V nominal for UCC2803-Q1) for error amplifier and internal functions; serves as logic power supply.
