L6565DTR from STMicroelectronics, 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 | INV | input | Inverting input of error amplifier for voltage feedback regulation via resistor divider or optocoupler; voltage range -0.3 to 7V. |
| 2 | COMP | output | Output of error amplifier for compensation network and PWM modulation control; voltage range -0.3 to 7V with upper clamp 5 to 5.5V and lower clamp 2.25 to 2.55V. |
| 3 | VFF | input | Line voltage feedforward input for adjusting current limitation setpoint via resistor divider; operating range 0 to 3V; ground pin to disable function and set maximum setpoint. |
| 4 | CS | input | Current sense input to PWM comparator; voltage range -0.3 to 7V; exceeding 2V threshold disables gate driver for hiccup-mode overcurrent protection. |
| 5 | ZCD | input | Transformer demagnetization or external synchronization input; negative-going edge below 1.6V triggers MOSFET turn-on after 2.1V positive arming threshold; blanked minimum 3.5µs after MOSFET turn-off; pull below 150mV to disable IC. |
| 6 | GND | power_in | Ground; current return for signal part of IC and gate driver circuits. |
| 7 | GD | output | Gate driver output with totem-pole stage; ±400mA peak source and sink current capability to drive MOSFETs and IGBTs; internal UVLO pull-down holds output low during UVLO. |
| 8 | Vcc | power_in | Supply voltage for signal circuits and gate driver; operating range 10.3 to 18V after turn-on with turn-on threshold 12.5 to 14.5V and turn-off threshold 8.7 to 10.3V. |
