Description and Introduction

Energy Efficient, CV or CV/CC Switcher for Very Low Cost Adapters and Chargers The LNK520GN is a part of the LinkSwitch-TN2 family from Power Integrations. Below are the factual specifications, descriptions, and features:

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

### **Specifications:**  
- **Input Voltage Range:** 85 VAC to 265 VAC  
- **Output Power:** Up to 3.5 W (non-isolated)  
- **Efficiency:** Up to 85% (depending on configuration)  
- **Switching Frequency:** 66 kHz  
- **Operating Temperature Range:** -40°C to +150°C (junction temperature)  
- **Package:** SMD (eSIP-7C)  

### **Descriptions:**  
- The LNK520GN is a highly integrated offline switcher IC designed for low-power, non-isolated buck and buck-boost applications.  
- It eliminates the need for a secondary-side feedback circuit by using primary-side regulation.  
- Suitable for LED drivers, auxiliary power supplies, and industrial controls.  

### **Features:**  
- **Primary-Side Regulation (PSR):** No optocoupler required.  
- **Auto-Restart Protection:** For output short-circuit and open-loop conditions.  
- **Frequency Jittering:** Reduces EMI filtering requirements.  
- **Thermal Shutdown:** Protects against overheating.  
- **Wide Input Voltage Range:** Supports universal mains input.  
- **High Efficiency:** Meets global energy efficiency standards.  

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