UCC28C58DR 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 for compensation/control with internal current limiting to GND for zero duty cycle. |
| 2 | FB | input | Inverting input to error amplifier used for power converter voltage-feedback loop stability with internal reference of 2.5V ± 1%. |
| 3 | CS | input | Primary-side current sense input to PWM comparator with cycle-by-cycle overcurrent limiting at 0.9-1.1V typical. |
| 4 | RT/CT | bidirectional | Oscillator timing pin for switching frequency setting by connecting external timing resistor to VREF and capacitor to GND. |
| 5 | GND | power_in | Ground return pin for output driver stage and logic level controller section. |
| 6 | OUT | output | Gate driver output delivering ±1A peak current with rail-to-rail swing (25ns rise, 20ns fall) to directly drive MOSFET. |
| 7 | VDD | power_in | Analog controller bias supply input rated to 28V maximum operating voltage requiring 0.1µF bypass capacitor to GND. |
| 8 | VREF | power_in | 5V precision reference output (±1% accurate) providing bias current to oscillator timing capacitor and requiring 0.1µF minimum bypass capacitor. |
