Description and Introduction

SMPS ICs for low-power systems The TEA1520P is a power supply controller IC manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 85V to 276V AC (universal mains)  
- **Output Power:** Up to 25W (depends on application)  
- **Switching Frequency:** Adjustable (typically 100 kHz)  
- **Start-Up Current:** Very low (typically 50 µA)  
- **Operating Current:** Low (typically 2.5 mA)  
- **Duty Cycle Range:** Up to 80%  
- **Protection Features:** Overvoltage, overcurrent, overtemperature, and undervoltage lockout (UVLO)  
- **Package:** DIP-8 (Dual In-line Package)  

### **Descriptions:**  
- The TEA1520P is a monolithic integrated circuit designed for flyback and buck converter applications.  
- It operates in quasi-resonant mode for improved efficiency and reduced EMI.  
- Suitable for low-power SMPS (Switched-Mode Power Supply) designs.  

### **Features:**  
- **High Efficiency:** Due to quasi-resonant switching.  
- **Low Standby Power Consumption:** Ideal for energy-saving applications.  
- **Integrated High-Voltage Startup Circuit:** Eliminates the need for an external startup resistor.  
- **Soft Start:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Frequency Jittering:** Reduces EMI emissions.  

The TEA1520P is commonly used in adapters, chargers, and auxiliary power supplies.
