OB2530PAP

OB On Bright Elec · AC-DC Controllers And Regulators · DIP-8

OB2530PAP from OB On Bright Elec, in a DIP-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 VDD power_in Power supply input: recommended VDD is 8 to 25 V, absolute maximum is -0.3 to 28 V, and VDD over-voltage protection trips at 26.0 to 28.0 V (27.0 V typ).
2 NC unconnected Listed as NC in the terminal assignment table, so no function is stated for this pin.
3 INV input Voltage feedback from the auxiliary winding through a resistor divider that reflects the output voltage; reference is Vref 2.475 to 2.525 V (2.500 V typ) and absolute maximum input is -0.3 to 7 V.
4 CS input Power MOSFET source and current-sense input; over-current threshold is 485 to 515 mV at minimum and up to 590 mV at maximum, with 300 ns leading-edge blanking, and absolute maximum input is -0.3 to 7 V.
5 Drain output Drain of the internal power MOSFET, rated for BVdss of 620 V; absolute maximum off-state drain voltage is -0.3 V to BVdss.
6 Drain output Drain of the internal power MOSFET (second drain pin, same net as pin 5), rated for BVdss of 620 V.
7 GND power_in Ground reference for the controller.
8 GND power_in Ground reference for the controller (second ground pin, same net as pin 7).
