Description and Introduction

Energy-Efficient, Accurate CV/CC Switcher for Adapters and Chargers The LNK603DG-TL is a part from the LinkSwitch-TN2 family, manufactured by Power Integrations.  

### **Manufacturer:**  
- **Power Integrations**  

### **Specifications:**  
- **Topology:** Buck, Buck-Boost, or Flyback  
- **Input Voltage Range:** 85 VAC to 265 VAC (universal input)  
- **Output Power:** Up to 6.5 W (depending on topology and conditions)  
- **Efficiency:** High efficiency (>80% typical)  
- **Switching Frequency:** 66 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C (junction temperature)  
- **Protection Features:**  
  - Auto-restart for output short-circuit and open-loop conditions  
  - Thermal shutdown  
  - Line undervoltage (brownout) protection  
  - Cycle-by-cycle current limit  

### **Descriptions:**  
- The LNK603DG-TL is an energy-efficient, offline switcher IC designed for low-power applications.  
- It integrates a 700 V power MOSFET, PWM controller, and protection features in a single package.  
- Suitable for non-isolated buck and buck-boost converters, as well as isolated flyback designs.  

### **Features:**  
- **Primary-Side Regulation (PSR):** Eliminates the need for an optocoupler in isolated designs.  
- **Frequency Jittering:** Reduces EMI filtering requirements.  
- **No-Load Consumption:** <50 mW (typical)  
- **Compact Design:** Requires minimal external components.  
- **Green-Mode Operation:** Reduces power consumption at light loads.  
- **SMD Package:** Available in SO-8C (LNK603DG-TL) for surface-mount applications.  

For detailed application notes and design guidelines, refer to the official Power Integrations datasheet.
