HVLED007TR from STMicroelectronics, in a SO-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	CT	passive	Input current shaper pin, where the capacitor to GND is alternately charged and discharged internally and its voltage sets the current-loop reference, with an operating range of 0 to 1.5 V and an upper clamp of 1.5 to 2.5 V.
2	COMP	input	Control input for PWM regulation, driven by an optocoupler phototransistor, with dynamics in the 2.5 to 5.5 V range, burst-mode operation below 2.5 V, and a bottom clamp of about 2.2 V.
3	MULT	input	Main multiplier input connected to the rectified mains voltage through a resistor divider, with an absolute maximum voltage range of -0.3 to 8 V.
4	CS	input	Input to the PWM comparator that senses the MOSFET current through a resistor and sets turn-off, with an absolute maximum voltage range of -0.3 to 8 V.
5	ZCD	input	Transformer demagnetization sensing input that triggers MOSFET turn-on on a negative-going edge, where a voltage above 5.5 V during OFF-time forces an overvoltage stop, with an absolute range of VZCDL to 8 V and a maximum source current of -3 mA.
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 rated for 600 mA source and 800 mA sink peak current, with its high level clamped at about 12 V.
8	VCC	power_in	Supply voltage for the signal part and gate driver, with an operating range of 10.5 to 22.5 V, a turn-on threshold of 11.7 to 13.3 V, and a Zener clamp of 22.5 to 28 V at 20 mA.
