DX5011D from Dersem, 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 | CS | input | Peak current sense input: the power MOSFET turns off when the CS voltage reaches the peak-current threshold VIPK (0.50 to 0.60 V, 0.55 V typical), and an abnormal over-current threshold VAOCP of 0.9 V shuts the MOSFET off for 48 us. |
| 2 | VDD | power_in | Chip supply pin that also serves as the output-voltage feedback point when FB is left open; VDD turns on at 7.5 V, undervoltage cutoff is 7.0 V, overvoltage protection trips at 28 V, the internal clamp is 30 V at 10 mA, and a 1 uF ceramic capacitor is recommended. |
| 3 | GND | power_in | Chip ground reference pin. |
| 4 | FB | input | Feedback input with internal reference VFB_REF of 2.0 V (1.97 to 2.03 V); leaving it floating selects the default 12 V output, and the overvoltage, overload and undervoltage thresholds are 2.4 V, 1.87 V respectively, with FB/CS pin voltage rated -0.3 to 7 V. |
| 5 | Drain | power_in | Drain of the internal high-voltage 500 V power MOSFET and high-voltage start-up circuit; the Drain pin voltage is rated -0.3 to 500 V. |
| 6 | Drain | power_in | Drain of the internal high-voltage 500 V power MOSFET and high-voltage start-up circuit; the Drain pin voltage is rated -0.3 to 500 V. |
| 7 | Drain | power_in | Drain of the internal high-voltage 500 V power MOSFET and high-voltage start-up circuit; the Drain pin voltage is rated -0.3 to 500 V. |
| 8 | Drain | power_in | Drain of the internal high-voltage 500 V power MOSFET and high-voltage start-up circuit; the Drain pin voltage is rated -0.3 to 500 V. |
