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.

Application Scenarios & Design Considerations

GreenChipTMII SMPS control IC

Alternative Part Number

  • NCP1200P60 --: Current-mode PWM controller in a DIP-8 package with similar offline flyback functionality; widely available and often used as a substitute in low-power SMPS designs.
  • UC3842AN --: Industry-standard current-mode PWM controller in DIP-8, pin-compatible in many flyback applications and easy to source as a functional replacement.
  • SG6848 --: Green-mode PWM controller for offline flyback converters with comparable control features and DIP-8 package, suitable for similar low-power adapter designs.
