# SS8202B

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

SS8202B 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, stabilized by a 4.7uF ceramic capacitor between VCC and GND; the absolute maximum VCC pin voltage is -0.3V to +10V and the internal clamp current is limited to 10mA. |
| 2 | GND | power_in | Chip ground pin serving as both power ground and signal ground; power ground and signal ground must be joined at a single point to the GND pin. |
| 3 | FB | input | Feedback sampling pin that directly senses the output voltage for constant-voltage control; the CS and FB pin voltage range is -0.3V to +6V and the internal reference is 2V. |
| 4 | CS | input | Current sense pin; a current sense resistor between CS and GND sets the required overcurrent point, and the CS and FB pin voltage range is -0.3V to +6V. |
| 5 | HVM | passive | Drain terminal of the built-in high-voltage MOSFET, with a maximum voltage of 900V. |
| 6 | HVM | passive | Drain terminal of the built-in high-voltage MOSFET, with a maximum voltage of 900V (pin 6 is bonded together with pin 5 as the HVM terminal). |
| 7 | NC | unconnected | No internal connection; leave floating. |
| 8 | HVJ | passive | Input to the built-in high-voltage JFET and resistor, with a maximum voltage of 1000V. |
