Description and Introduction

GreenChipTMII SMPS control IC The TEA1533AT is a power management IC manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Input Voltage Range:** 70V to 276V AC (universal mains)  
- **Switching Frequency:** Adjustable, typically up to 100kHz  
- **Output Power:** Up to 25W (depending on design)  
- **Operating Temperature Range:** -25°C to +150°C  
- **Package:** SO16 (Small Outline 16-pin)  

### **Descriptions:**  
- The TEA1533AT is a green-mode SMPS (Switched-Mode Power Supply) controller.  
- It is designed for flyback converters in low-power applications.  
- Includes built-in protections like overvoltage, overcurrent, and overtemperature.  

### **Features:**  
- **High Efficiency:** Green-mode operation for reduced standby power.  
- **Soft Start:** Prevents inrush current at startup.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Overvoltage Protection (OVP):** Safeguards against voltage spikes.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Low Standby Power Consumption:** Meets energy-saving standards.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
