OB2530TAP 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 pin with a recommended operating range of 8 to 25 V, UVLO thresholds of 8.3 V (on) and 16.5 V (off) typical, and VDD over-voltage protection at 27.0 V typical (26.0 to 28.5 V). |
| 2 | NC | unconnected | No connection; the datasheet lists no function for this pin. |
| 3 | INV | input | Voltage feedback input from the auxiliary winding through a resistor divider that reflects the output voltage, compared with a 2.500 V typical reference (2.475 to 2.525 V). |
| 4 | CS | input | Power MOSFET source and current-sense input for the external sense resistor Rs, with a 300 ns leading edge blanking time and over-current threshold between 500 mV and 590 mV. |
| 5 | Drain | output | Drain of the internal power MOSFET, rated at 620 V BVdss and 2 Ω static Rdson for the OB2530TAP. |
| 6 | Drain | output | Drain of the internal power MOSFET (pin 6 is internally shared with pin 5 per the terminal assignment), rated at 620 V BVdss and 2 Ω static Rdson for the OB2530TAP. |
| 7 | GND | power_in | Ground reference pin for the device. |
| 8 | GND | power_in | Ground reference pin for the device (pin 8 is listed together with pin 7 as GND in the terminal assignment). |
