UCC2805DTR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | COMP | output | Error amplifier output and PWM comparator input; low-impedance 2MHz operational amplifier capable of sourcing and sinking current. |
| 2 | FB | input | Error amplifier inverting input; keep trace length and stray capacitance as small as possible for optimal stability. |
| 3 | CS | input | Current-sense comparator input with 100ns leading edge blanking after OUT rising edge to suppress switching transients. |
| 4 | RC | input | Oscillator timing pin; frequency determined by RC network with recommended 10kΩ to 200kΩ resistor and 100pF to 1000pF capacitor. |
| 5 | GND | power_in | Reference ground and power supply ground for all device functions. |
| 6 | OUT | output | High-current gate driver output capable of peak current exceeding ±750mA; actively held low when VCC below threshold; CMOS output with low impedance. |
| 7 | VCC | power_in | Power supply input through current-limiting resistor; internally regulated to approximately 13.5V by on-chip Zener diode. |
| 8 | REF | output | 4V reference voltage output for error amplifier and logic circuits; pulled low through 5kΩ when VCC between 1V and UVLO threshold. |
