Description and Introduction

STARplug The **TEA1522** is a power supply controller IC manufactured by **PHILIPS** (now NXP Semiconductors). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 70V to 276V AC (universal mains operation)  
- **Output Power:** Up to 15W (depends on design)  
- **Switching Frequency:** Adjustable (typically 100kHz)  
- **Standby Power Consumption:** <1W  
- **Operating Temperature Range:** -25°C to +125°C  
- **Package Type:** DIP-8 or SO-8  

### **Descriptions:**
- The **TEA1522** is a low-cost, highly integrated **SMPS (Switched-Mode Power Supply)** controller for flyback and buck converter topologies.  
- It is designed for **low-power offline power supplies** in applications like adapters, chargers, and auxiliary power supplies.  
- The IC includes **built-in protections** such as overvoltage, overcurrent, and overtemperature shutdown.  

### **Features:**
- **High Efficiency:** Optimized for energy-saving designs.  
- **Soft Start:** Reduces inrush current during startup.  
- **Frequency Jittering:** Minimizes EMI interference.  
- **Current-Mode Control:** Ensures stable operation.  
- **Low Startup Current:** Enables fast power-up.  
- **Integrated High-Voltage Startup Circuit:** Simplifies external circuitry.  

The **TEA1522** is widely used in **consumer electronics, LED drivers, and small power supplies** due to its reliability and cost-effectiveness.  

*(Note: PHILIPS' semiconductor division became NXP Semiconductors, but the TEA1522 retains its original branding.)*
