TL3842P from Texas Instruments, in a DIP-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 | bidirectional | Error amplifier compensation pin with output current 2 to 6 mA sink or 0.5 to 0.8 mA source capability |
| 2 | VFB | input | Error amplifier feedback input for output voltage regulation, operating range 0 to 5.5 V |
| 3 | ISENSE | input | Current sense comparator input with 2.85 to 3.15 V/V transconductance and 0.9 to 1.1 V threshold |
| 4 | RT/CT | bidirectional | Oscillator RC timing network input for fixed-frequency clock generation, operating range 0 to 5.5 V |
| 5 | GND | power_in | Device power supply ground terminal |
| 6 | OUTPUT | output | PWM output stage with ±1 A peak current drive capability for N-channel MOSFET gate, 0 to 30 V output range |
| 7 | VCC | power_in | Device positive voltage supply, 30 V maximum recommended operating voltage |
| 8 | REF | output | Precision 5 V oscillator voltage reference output with 4.9 to 5.1 V accuracy for TL3842 |
