L6565D from STMicroelectronics, in a SOIC-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; accepts output voltage feedback through resistor divider or optocoupler for primary or secondary regulation; operating range -0.3 to 7V. |
| 2 | COMP | output | Output of the error amplifier for loop compensation network; upper clamp voltage 5.5V, lower clamp voltage 2.25V; operating range -0.3 to 7V. |
| 3 | VFF | input | Line voltage feedforward input; modulates pulse-by-pulse current limitation setpoint based on converter input voltage through resistor divider; operating range 0 to 3V. |
| 4 | CS | input | Current sense input to PWM comparator; primary current sensed through resistor is compared to internal reference to determine MOSFET turn-off; hiccup-mode OCP triggered at 2.0V; operating range -0.3 to 7V. |
| 5 | ZCD | input | Transformer demagnetization sensing input for quasi-resonant operation or external synchronization; negative-going edge below 1.6V triggers MOSFET turn-on after arming at positive-going edge above 2.1V; trigger blanked 3.5µs minimum after MOSFET turn-off. |
| 6 | GND | power_in | Ground; current return for both signal part of the IC and gate driver. |
| 7 | GD | output | Gate driver totem pole output stage; drives power MOSFET or IGBT with ±400mA peak current capability (source and sink). |
| 8 | VCC | power_in | Supply voltage input for signal and gate driver circuits; operating range after turn-on 10.3 to 18V with UVLO thresholds; electrolytic capacitor typically connected between this pin and ground. |
