UCC2800QDRQ1 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; true low output impedance 2MHz operational amplifier capable of sourcing and sinking current with internal current limiting allowing zero duty cycle by external connection to GND. |
| 2 | FB | input | Inverting input of error amplifier for feedback voltage regulation; keep lead length as short as possible and minimize stray capacitance for best stability. |
| 3 | CS | input | Current sense input to PWM and overcurrent comparators with internal 100ns digital leading edge blanking for noise rejection; no external RC filtering required in most applications. |
| 4 | RC | input | Oscillator timing pin; connect external resistor from REF (10kΩ to 200kΩ recommended) to set timing capacitor charging current and capacitor to GND (100pF to 1000pF recommended) to set switching frequency. |
| 5 | GND | power_in | Reference ground and power ground for all device functions; use ground plane and keep separate ground paths for high-current gate driver circuit. |
| 6 | OUT | output | High-current power driver output with peak current capability exceeding ±750mA for driving MOSFET gates; actively held low when VCC is below UVLO threshold; CMOS output with low impedance for overshoot and undershoot suppression. |
| 7 | VCC | power_in | Power supply input biased through series current-limiting resistor in normal operation; internal clamp to 13.5V; typical quiescent current 500µA; requires 0.1µF ceramic capacitor bypassed to GND near pin. |
| 8 | REF | output | Reference voltage output (5V for UCC2800-Q1) providing precision voltage reference for error amplifier and internal circuits; pulled to ground through 5kΩ resistor during UVLO; requires 0.1µF minimum ceramic bypass capacitor to GND. |
