Description and Introduction

Synchronous rectification controller with integrated feedback and protection The TEA1762T is a GreenChip III SMPS controller IC manufactured by NXP Semiconductors. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 8.5 V to 38 V  
- **Standby Power Consumption:** < 30 mW  
- **Switching Frequency:** Adjustable up to 250 kHz  
- **Maximum Duty Cycle:** 80%  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** SO16  

### **Descriptions:**
The TEA1762T is a highly integrated flyback controller designed for low-power AC/DC adapters and chargers. It operates in quasi-resonant mode for improved efficiency and reduced EMI. The IC includes multiple protection features such as overvoltage protection (OVP), overcurrent protection (OCP), and overtemperature protection (OTP).  

### **Features:**
- **High Efficiency:** Quasi-resonant operation for minimal switching losses.  
- **Low Standby Power:** Meets energy efficiency standards (e.g., ENERGY STAR).  
- **Integrated Protections:**  
  - Overvoltage protection (OVP)  
  - Overcurrent protection (OCP)  
  - Overtemperature protection (OTP)  
  - Short-circuit protection  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Soft Start:** Prevents inrush current at startup.  
- **Burst Mode Operation:** Enhances efficiency at light loads.  

This information is based on NXP's official documentation for the TEA1762T.
