OB3398ETAP-H 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 | GND | power_in | Ground reference pin for the device. |
| 2 | NC | unconnected | No connect; the datasheet lists this pin as not connected internally. |
| 3 | CS | input | Current sense input; the LED constant current is set externally by resistor Rs at this pin, and the CS input voltage is limited to -0.3 V to 7 V. |
| 4 | FB | input | Connected to a resistor divider from the primary or auxiliary winding to reflect the output voltage, with the FB input voltage limited to -0.3 V to 7 V. |
| 5 | VDD | power_in | Power supply pin with a recommended supply range of 12 V to 25 V and an absolute maximum range of -0.3 V to VDD_clamp. |
| 6 | Drain | output | Drain of the internal high-voltage power MOSFET, with drain voltage limited to -0.3 V to BVdss. |
| 7 | Drain | output | Drain of the internal high-voltage power MOSFET, with drain voltage limited to -0.3 V to BVdss. |
| 8 | Drain | output | Drain of the internal high-voltage power MOSFET, with drain voltage limited to -0.3 V to BVdss. |
