L6565N 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, fed with output voltage information through a resistor divider (primary regulation) or an optocoupler (secondary feedback), and may be grounded in some secondary feedback schemes. |
| 2 | COMP | output | Error amplifier output, normally compensated to INV, and with secondary feedback it can be driven directly by an optocoupler that modulates PWM by sinking current from the pin with INV grounded. |
| 3 | VFF | input | Line voltage feedforward input that lowers the pulse-by-pulse current limit setpoint as the input voltage rises (operating range 0 to 3 V), and is grounded to disable the function so the setpoint stays at maximum. |
| 4 | CS | input | Input to the PWM comparator that senses primary current through a resistor to set MOSFET turn-off, and if the signal exceeds 2 V the gate driver is disabled (Hiccup-mode OCP). |
| 5 | ZCD | input | Transformer demagnetization sensing input for quasi-resonant operation or an external sync input, where a negative-going edge triggers MOSFET turn-on, the trigger is blanked for a minimum of 3.5 µs after turn-off, and grounding the pin disables the IC. |
| 6 | GND | power_in | Ground, serving as the current return for both the signal part of the IC and the gate driver. |
| 7 | GD | output | Totem-pole gate driver output able to drive power MOSFETs and IGBTs with a peak current of 400 mA source and sink. |
| 8 | VCC | power_in | Supply voltage for the signal part and the gate driver, requiring an electrolytic capacitor to ground, with an operating range of 10.3 to 18 V after turn-on. |
