TL2842DR-8 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 | bidirectional | Error amplifier compensation pin for feedback network impedance; can source or sink up to 0.5 mA. |
| 2 | VFB | input | Error amplifier input terminal with nominal 2.5 V setpoint and input voltage range 0 to 5.5 V. |
| 3 | ISENSE | input | Current sense comparator input with 1 V threshold and 3 V/V gain, input voltage range 0 to 5.5 V. |
| 4 | RT/CT | bidirectional | Oscillator RC timing input for external frequency-setting resistor and capacitor, voltage range 0 to 5.5 V. |
| 5 | GND | power_in | Device power supply ground terminal and reference potential for all internal circuits. |
| 6 | OUTPUT | output | PWM output terminal driving N-channel MOSFETs with 0 to 30 V range, sourcing/sinking up to 1 A. |
| 7 | VCC | power_in | Device positive voltage supply terminal with recommended operating range 30 V maximum. |
| 8 | REF | output | Oscillator voltage reference output providing 5 V typical with short-circuit current -30 to -180 mA. |
