GP7585B from HaloChip, in a SOP-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	GND	power_in	Chip ground; the datasheet absolute maximum for the VCC pin is 6 V and the recommended VCC operating voltage is 5 V.
2	GND	power_in	Chip ground, bonded together with pins 1 and 3; the datasheet gives no separate limit for this pin.
3	GND	power_in	Chip ground, bonded together with pins 1 and 2; the datasheet gives no separate limit for this pin.
4	VCC	power_in	Chip power supply that must be bypassed by a capacitor placed close to the pin; the datasheet gives VCC operating voltage 5 V, clamp voltage 6 V, UVLO(ON) 2.8 V and UVLO(OFF) 3.7 V.
5	SW	passive	Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended.
6	SW	passive	Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended.
7	SW	passive	Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended.
8	SW	passive	Drain of the internal power MOSFET; the SW pin operating voltage is limited to 45 V absolute maximum and 4.7 to 40 V recommended.
