UCC2893PWR from Texas Instruments, in a TSSOP-16. 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 | RTDEL | input | Resistor to GND sets turn-on delay between OUT and AUX gate drive outputs. |
| 2 | RTON | input | Resistor to GND programs charge current for internal oscillator timing capacitor. |
| 3 | RTOFF | input | Resistor to GND programs discharge current for internal oscillator timing capacitor. |
| 4 | VREF | power_in | 5-V reference voltage output with 5-mA external load capability. |
| 5 | SYNC | input | Unidirectional synchronization input for locking internal oscillator to external clock. |
| 6 | GND | power_in | Analog ground reference for control and programming circuitry. |
| 7 | CS | input | Current sense input to PWM comparator and cycle-by-cycle current limiting circuit. |
| 8 | RSLOPE | input | Resistor to GND sets slope compensation ramp amplitude for current mode control. |
| 9 | FB | input | Feedback input from external error amplifier or optocoupler for PWM modulation. |
| 10 | SS/SD | input | Soft-start capacitor charging pin; also used for shutdown control and soft-stop. |
| 11 | PGND | power_in | Power ground for high-current gate drivers and output protection circuitry. |
| 12 | AUX | output | Auxiliary switch gate drive output with 2-A source and 2-A sink current capability. |
| 13 | OUT | output | Main power switch gate drive output with 2-A source and 2-A sink current capability. |
| 14 | VDD | power_in | Power supply for internal circuits, operating range 8.5 to 16.0 V with 1-µF bypass capacitor. |
| 15 | LINEUV | input | Line undervoltage monitoring input with 1.27-V threshold for shutdown control. |
| 16 | VIN | power_in | High-voltage startup input up to 110 V for initial bias power via internal JFET regulator. |
