DK5710 from Shenzhen DongKe Semicon, 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 | VDD | power_in | Chip power supply pin, with a start threshold of 10.5 V typ (9.5 to 11.5 V), undervoltage protection below 9 V, a clamp of 24 to 28 V, and an absolute maximum VDD supply voltage of 28 V. |
| 2 | GND | power_in | Ground pin; the VDD capacitor EC2 should be placed as close as possible to the VDD and GND pins. |
| 3 | FB | input | Feedback pin that samples the output voltage through the external divider to set the 3.3 V to 24 V output, where FB below 1.7 V for 50 ms triggers overload protection and FB below 200 mV after soft-start triggers FB fault restart. |
| 4 | NC | unconnected | No-connect pin, listed as an empty (NC) pin in the datasheet. |
| 5 | SW | passive | High-voltage MOSFET drain pin, with a drain-source breakdown voltage BVDSS of 680 V min and a maximum drain-source voltage rating VDRAIN_MAX of 680 V. |
| 6 | SW | passive | High-voltage MOSFET drain pin, with a drain-source breakdown voltage BVDSS of 680 V min and a maximum drain-source voltage rating VDRAIN_MAX of 680 V. |
| 7 | SW | passive | High-voltage MOSFET drain pin, with a drain-source breakdown voltage BVDSS of 680 V min and a maximum drain-source voltage rating VDRAIN_MAX of 680 V. |
| 8 | SW | passive | High-voltage MOSFET drain pin, with a drain-source breakdown voltage BVDSS of 680 V min and a maximum drain-source voltage rating VDRAIN_MAX of 680 V. |
