Description and Introduction

Synchronous rectification controller suitable for both high-side and low-side control The TEA1791T is a controller IC manufactured by NXP Semiconductors. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
1. **Type**: GreenChip SMPS controller IC  
2. **Function**: Primary-side controller for switched-mode power supplies (SMPS)  
3. **Topology**: Flyback converter  
4. **Input Voltage Range**: Typically operates with universal mains input (85 VAC to 265 VAC)  
5. **Switching Frequency**: Adjustable, typically up to 300 kHz  
6. **Operating Temperature Range**: -40°C to +125°C  
7. **Package**: SO8 (Small Outline 8-pin package)  
8. **Protection Features**:  
   - Overvoltage protection (OVP)  
   - Overcurrent protection (OCP)  
   - Overtemperature protection (OTP)  
   - Undervoltage lockout (UVLO)  

### **Descriptions:**
- The TEA1791T is designed for energy-efficient power supplies, particularly in standby and low-power applications.  
- It integrates multiple control and protection functions to simplify SMPS designs.  
- The IC supports quasi-resonant operation for improved efficiency.  

### **Features:**
1. **High Efficiency**: Optimized for low standby power consumption.  
2. **Quasi-Resonant Operation**: Reduces switching losses.  
3. **Frequency Reduction Mode**: Enhances efficiency at light loads.  
4. **Integrated Protections**: Built-in safeguards for reliable operation.  
5. **Low Start-up Current**: Enables fast and reliable power-up.  
6. **Green Mode Operation**: Minimizes power dissipation in standby mode.  

This information is based on NXP's official documentation for the TEA1791T. For exact values and application details, refer to the datasheet.
