Texas Instruments · AC-DC Controllers And Regulators · SOIC-8
UCC2813D-5 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 with 2MHz bandwidth serving as PWM comparator input for feedback loop compensation. |
| 2 | FB | input | Error amplifier inverting input for closed-loop output voltage feedback regulation signal. |
| 3 | CS | input | Current sense input to PWM and overcurrent comparators; includes 100ns leading-edge blanking to suppress transient noise. |
| 4 | RC | input | Oscillator timing pin accepting external RC network; switching frequency programmable to 1MHz maximum via timing resistor and capacitor. |
| 5 | GND | power_in | Power supply and signal ground reference for all circuit functions. |
| 6 | OUT | output | Gate driver output providing ±750mA to ±1A peak current to MOSFET gates; held low during UVLO without external pull-down resistor. |
| 7 | VCC | power_in | Positive power supply input nominally 10V; internally clamped to 13.5V maximum, requires 0.1µF ceramic bypass capacitor. |
| 8 | REF | power_out | 4V precision reference output (±1.5% accuracy at 25°C for UCC2813-5 variant) biasing error amplifier and logic circuits; requires 0.1µF minimum bypass capacitor. |
