KP1220SPA from Kiwi Instruments, in a SOP-7. 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 COMP input Constant-current output loop compensation pin. Recommended to connect a 1-4.7uF ceramic capacitor in series with a resistor to the reference ground of the chip; the series resistor sets the over-current protection threshold. Internal clamp: Vcomp_H=3V, Vcomp_L=0.7V.
2 GND power_in Chip reference ground.
3 VDD power_in Chip supply pin. Normal operating voltage 10.5-13V (typ 11.5V); UVLO trip at 7.5-9.0V; internal clamp at 14V. Startup current 300uA typ, operating current 200uA typ at Fsw=7kHz.
4 ROVP input Output open-circuit protection voltage setting pin. A resistor divider on this pin programs the output OVP threshold. Absolute max -0.3 to 7V.
5 Drain passive Drain of the internal high-voltage MOSFET (500V VBR). Also used for HV startup charging (IHV=10mA at Drain=20V). Tied together with pin 6.
6 Drain passive Drain of the internal high-voltage MOSFET (500V VBR). Tied together with pin 5.
7 Source output Source output of the internal high-voltage MOSFET. Used for peak current sensing (VCC_REF=400mV typ constant-current reference, Vcs_min=70mV typ). Absolute max -0.3 to 7V.
