DK1203 from Shenzhen DongKe Semicon, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OB | input | Startup pin with internal startup circuit connected to high-voltage OC pins; leave unconnected in typical application. |
| 2 | VCC | power_in | Power supply pin; externally connect 10µF~100µF storage capacitor to ground. |
| 3 | GND | power_in | Ground pin. |
| 4 | NC | unconnected | Empty pin with no internal electrical connection. |
| 5 | FB | input | Feedback control pin; connect 1nF~10nF capacitor to ground; photo-coupler controls output to ground. |
| 6 | NC | unconnected | Empty pin with no internal electrical connection. |
| 7 | OC | output | Output pin connected to internal high-voltage power transistor; externally connected to switching transformer; high-voltage up to 600V+. |
| 8 | OC | output | Output pin connected to internal high-voltage power transistor; externally connected to switching transformer; high-voltage up to 600V+. |
