OB2263M from HGSEMI, 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 | GATE | output | Gate drive output connected to the power MOSFET gate, clamped at 14.5 V with 175 ns rise and 85 ns fall times at 1000 pF load. |
| 2 | VDD | power_in | IC supply pin with a recommended supply range of 10 V to 26 V, a 30 V absolute maximum, and a 30 V clamp at 10 mA. |
| 3 | NC | unconnected | No internal connection. |
| 4 | CS | input | Current sense input whose resistance to ground sets the maximum output power of the system, with an absolute maximum of -0.3 V to 5 V. |
| 5 | RI | passive | Switching-frequency setting pin where a resistor to GND sets the frequency (100 kΩ gives 65 kHz), with a recommended range of 50 to 150 kHz. |
| 6 | NC | unconnected | No internal connection. |
| 7 | FB | input | Feedback input whose voltage sets PWM duty and the green-mode (2.1 V) and burst-mode (1.25 V enter, 1.35 V exit) thresholds, with an absolute maximum of -0.3 V to 5 V. |
| 8 | GND | power_in | Ground reference for the IC and the RI resistor return. |
