L6561 from STMicroelectronics, 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 | INV | input | Inverting input of the error amplifier; a resistive divider is connected between the output regulated voltage and this point to provide voltage feedback. |
| 2 | COMP | output | Output of error amplifier; a feedback compensation network is placed between this pin and the INV pin. |
| 3 | MULT | input | Input of the multiplier stage; a resistive divider connects to this pin the rectified mains and a voltage signal proportional to the rectified mains appears on this pin. |
| 4 | CS | input | Input to the comparator of the control loop; the current is sensed by a resistor and the resulting voltage is applied to this pin. |
| 5 | ZCD | input | Zero current detection input; if it is connected to GND, the device is disabled. |
| 6 | GND | power_in | Current return for driver and control circuits. |
| 7 | GD | output | Gate driver output; a push pull output stage is able to drive the Power MOS with peak current of 400mA (source and sink). |
| 8 | VCC | power_in | Supply voltage of driver and control circuits; operating range 11V to 18V per electrical characteristics. |
