DK106 — AC-DC Power Control IC by Dongke Semiconductor
9W | 85V–265V Input | DIP-8 / SOP-8 | In Stock | Authorized Distribution across India
What Is the DK106?
The DK106 is a compact, high-efficiency AC-DC Flyback Power Supply Control IC from Dongke Semiconductor (DK) — purpose-built for low-to-medium power applications including LED drivers, small adapters, and home appliance power boards. It converts high-voltage AC input (85V–265V) into stable, regulated low-voltage DC output, delivering up to 9W in open environments and 6W in enclosed designs.
With a built-in 700V power transistor and self-powered technology, the DK106 requires no external auxiliary winding — making it the ideal choice for cost-sensitive, space-constrained designs where simplicity and reliability are equally critical.
Key Features
- ⚡ Up to 9W output power — 9W open frame / 6W enclosed
- 🔌 Built-in 700V power transistor — no extra high-voltage components required
- 🔧 Self-powered technology — no external auxiliary winding, simplifying transformer design
- 🌱 Standby power < 0.3W — meets European ErP energy efficiency standards
- 🛡️ Comprehensive protection — over-temperature (125°C), overvoltage, short circuit, overload & secondary open circuit protection
- 📡 Frequency jitter technology — reduces EMI interference, lowering filtering costs
- 📐 Built-in slope compensation — ensures circuit stability at low voltage and high output conditions
- 🚀 Soft start — prevents voltage spikes and transformer saturation at startup
- 🔒 ESD Rating: 4KV — robust protection during manufacturing and handling
