Shenzhen Sunmoon Micro · AC-DC Controllers & Regulators · DIP-8
SM7022 from Shenzhen Sunmoon Micro, 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 | Chip ground, which is also the SOURCE terminal of the internal high-voltage MOS transistor. |
| 2 | GND | power_in | Chip ground, which is also the SOURCE terminal of the internal high-voltage MOS transistor. |
| 3 | FB | input | Feedback input terminal, with a maximum feedback current of 3 mA. |
| 4 | VDD | power_in | Chip supply terminal with an operating voltage range of 9V to 30V. |
| 5 | DRAIN | passive | Drain of the internal high-voltage MOS transistor, also used for chip startup, with an absolute maximum of -0.3 to 730 V (-0.3 to 400 V during startup). |
| 6 | DRAIN | passive | Drain of the internal high-voltage MOS transistor, also used for chip startup, with an absolute maximum of -0.3 to 730 V (-0.3 to 400 V during startup). |
| 7 | DRAIN | passive | Drain of the internal high-voltage MOS transistor, also used for chip startup, with an absolute maximum of -0.3 to 730 V (-0.3 to 400 V during startup). |
| 8 | DRAIN | passive | Drain of the internal high-voltage MOS transistor, also used for chip startup, with an absolute maximum of -0.3 to 730 V (-0.3 to 400 V during startup). |
