KP1199BWPA from Kiwi Instruments, in a SOP-7-150mil. 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	ACIN	power_in	AC line input pin (input voltage pin). One of two ACIN pins connected to the internal 800V rectifier bridge. Absolute max voltage: -0.3 to 800 V.
2	GND	power_in	Chip reference ground.
3	ROVP	input	Output overvoltage protection setting pin. A resistor to GND (recommended 5K~14K) sets the OVP threshold. When ROVP is left floating it is equivalent to ROVP=14K. Also functions as an enable input: when V_ROVP < 50 mV the chip is disabled (shutdown). ROVP output current typ. 40 uA.
4	CS	output	Internal power MOSFET source output and current-sense input pin. Connect an external sense resistor Rcs from CS to GND to set the peak primary current (Vcs(max) typ. 600 mV). Absolute max voltage: -0.3 to 7 V.
5	Drain	input	Internal 650V power MOSFET drain input pin. Connects to the flyback transformer primary. Rdson typ. 16 Ω (KP1199BWPA). Absolute max voltage: -0.3 to 650 V.
6	HV	power_in	High-voltage supply input pin (HVDD). Provides internal MOSFET gate-drive supply via the on-chip high-voltage self-supply circuit; no external VDD capacitor required. HV_DD_ON typ. 15.5 V, HV_DD_OFF typ. 8.0 V. Absolute max: -0.3 to 650 V.
7	ACIN	power_in	AC line input pin (input voltage pin). Second of two ACIN pins connected to the internal 800V rectifier bridge. Absolute max voltage: -0.3 to 800 V.
