UCC28085DR 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 | CTRL | input | Error voltage input to PWM comparator, −0.3 V to VDD + 0.3 V. |
| 2 | ISET | input | Current selection input for slope compensation; voltage tracks the 1.5-V internal oscillator ramp. |
| 3 | CS | input | Current-sense input to PWM comparator and overcurrent comparator, −0.3 V to VDD + 0.3 V (not to exceed 6 V); internal MOSFET discharges filter capacitor. |
| 4 | RT | input | Oscillator programming pin, −0.3 V to 2.0 V, −100 µA < IRT < 100 µA. |
| 5 | GND | power_in | Reference and power ground for all functions. |
| 6 | OUTB | output | Alternating high-current output stage, 1.0-A peak-sink current and 0.5-A peak-source current. |
| 7 | OUTA | output | Alternating high-current output stage, 1.0-A peak-sink current and 0.5-A peak-source current. |
| 8 | VDD | power_in | Power input connection, 15 V maximum (IDD < 10 mA). |
