SS8201B

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

SS8201B from orisilicon, 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 VCC power_in Chip supply pin, decoupled with a 4.7uF ceramic capacitor between VCC and GND; the internal 10V regulator clamps VCC and the datasheet gives an absolute maximum of -0.3V to +10V.
2 GND power_in Chip ground pin that serves as both the power ground and the signal ground, with the power and signal grounds connected at a single point to this pin.
3 FB input Feedback sampling pin that directly senses the output voltage for constant-voltage control, with an absolute voltage range of -0.3V to +6V.
4 CS input Current sense pin, where the current sense resistor between CS and GND sets the overcurrent point and the absolute voltage range is -0.3V to +6V.
5 HVM passive Built-in high-voltage MOS drain terminal with an absolute maximum voltage of 800V.
6 HVM passive Built-in high-voltage MOS drain terminal with an absolute maximum voltage of 800V.
7 NC unconnected Not connected; this pin is left floating.
8 HVJ passive Built-in high-voltage JFET and resistor input pin with an absolute maximum voltage of 1000V, used for high-voltage startup from the bus.
