OB2263M

HGSEMI · AC-DC Controllers And Regulators · SOP-8

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.
