DK1203

Shenzhen DongKe Semicon · AC-DC Controllers And Regulators · DIP-8

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+.
