L6565DTR

STMicroelectronics · AC-DC Controllers And Regulators · SOIC-8

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.
