UC2842BD1013TR from STMicroelectronics, in a SO-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 external compensation network, output range 0V to 6V |
| 2 | VFB | input | Inverting input of error amplifier for proportional power supply feedback control |
| 3 | ISENSE | input | Current sense input for PWM cycle-by-cycle current limiting, maximum input signal 1V |
| 4 | RT/CT | passive | Oscillator timing capacitor node where external RT resistor connects to VREF and CT capacitor to ground for frequency programming to 500kHz maximum |
| 5 | GROUND | power_in | Control circuitry and power ground reference |
| 6 | OUTPUT | output | PWM output driver for N-channel MOSFET gate, peak current ±1A, 50-150ns rise/fall time at 1nF load |
| 7 | VCC | power_in | Positive supply voltage with UVLO start threshold 16V typical and minimum operating voltage 10V typical, absolute maximum 30V |
| 8 | VREF | power_in | Precision 5V reference output with 50mA source capability for timing and bias circuits |
