OB On Bright Elec · AC-DC Controllers And Regulators · SOT-23-6

OB2560MP from OB On Bright Elec, in a SOT-23-6. 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	FB	input	Voltage feedback input from the auxiliary winding, driven through a resistor divider that reflects the output voltage; absolute maximum input voltage is -0.3 to 7V.
2	GND	power_in	Ground reference pin for the controller.
3	RT	input	Connected through an NTC resistor to ground for over-temperature shutdown; absolute maximum input voltage is -0.3 to 7V.
4	CS	input	Power MOSFET source and current-sense input; the sense resistor Rs at this pin sets the constant-current level; absolute maximum input voltage is -0.3 to 7V.
5	GATE	output	Gate driver output for the external power MOSFET; absolute maximum voltage is -0.3 to 24V.
6	VDD	power_in	Power supply pin; recommended supply range is 9 to 22V, with an absolute maximum of -0.3 to 30V.
