VIPER12A from Minos, 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 | GND | power_in | Ground pin (地) of the controller, listed in the pin function table as pin 1 of the DIP8 package. |
| 2 | GND | power_in | Ground pin (地) of the controller, listed in the pin function table as pin 2 of the DIP8 package; the pin diagram text labels this position as DRAIN, so verify against the physical package. |
| 3 | COMP | input | Feedback input (反馈输入端): COMP shutdown threshold is 1.1 V min, 1.2 V typ, 1.3 V max, input impedance is 1.0 kΩ typ, and the feedback withstand voltage (VCOMP) is -0.3 V to 6 V. |
| 4 | VDD | power_in | Supply pin (电源端): operating range is 10 V to 35 V, start-up threshold VDD_ON is 13 V to 17 V, undervoltage shutdown VDD_OFF is 7 V to 9 V, overvoltage protection VDD_OVP is 36 V to 44 V, and the absolute maximum rating is -0.3 V to 45 V. |
| 5 | DRAIN | output | Output pin connected to the switching transformer, driving the internal 800 V power MOSFET (VBVDSS minimum 800 V, Rdson typical 10 Ω at ID = 1 A); absolute maximum DRAIN voltage is -0.3 V to 800 V. |
| 6 | DRAIN | output | Output pin connected to the switching transformer, driving the internal 800 V power MOSFET (VBVDSS minimum 800 V, Rdson typical 10 Ω at ID = 1 A); absolute maximum DRAIN voltage is -0.3 V to 800 V. |
| 7 | DRAIN | output | Output pin connected to the switching transformer, driving the internal 800 V power MOSFET (VBVDSS minimum 800 V, Rdson typical 10 Ω at ID = 1 A); absolute maximum DRAIN voltage is -0.3 V to 800 V. |
| 8 | DRAIN | output | Output pin connected to the switching transformer, driving the internal 800 V power MOSFET (VBVDSS minimum 800 V, Rdson typical 10 Ω at ID = 1 A); absolute maximum DRAIN voltage is -0.3 V to 800 V. |
