OB2263N from HGSEMI, 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 | GATE | output | Drive pin that connects to the power MOSFET gate; it has an internal pull-down, and the gate clamp is stated as 14.5 V (typ.) with a rise time of 175 ns and fall time of 85 ns at CL=1000pF. |
| 2 | VDD | power_in | IC power supply pin; recommended supply range is 10 V to 26 V, absolute maximum is 30 V, with 4.7 to 10 uF VDD capacitance and UVLO/OVP thresholds of 8.0 V (typ.) and 28.0 V (typ.). |
| 3 | NC | unconnected | No connection. |
| 4 | CS | input | Current sense pin; absolute maximum voltage is -0.3 V to 5 V, and the resistor between this pin and GND sets the maximum output power of the system. |
| 5 | RI | input | Switching frequency setting pin; a resistor from this pin to GND sets the switching frequency (65 kHz with RI = 100 kΩ, recommended operating range 50 to 150 kHz), and absolute maximum voltage is -0.3 V to 5 V. |
| 6 | NC | unconnected | No connection. |
| 7 | FB | input | Feedback pin that sets PWM duty cycle together with CS and controls burst, green and power-limit modes; absolute maximum voltage is -0.3 V to 5 V. |
| 8 | GND | power_in | Ground reference for the controller. |
