Description and Introduction

Synchronous rectification controller with integrated feedback and protection The TEA1761T is a controller IC manufactured by NXP Semiconductors, designed for flyback converters in power supply applications. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 8.5V to 38V  
- **Switching Frequency:** Up to 250 kHz  
- **Standby Power Consumption:** <30 mW  
- **Maximum Output Power:** Up to 25W (depending on design)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO16  

### **Descriptions:**  
- The TEA1761T is a green-mode flyback controller with integrated high-voltage startup and low standby power.  
- It supports quasi-resonant operation for improved efficiency and reduced EMI.  
- Includes protection features such as overvoltage protection (OVP), overcurrent protection (OCP), and overtemperature protection (OTP).  

### **Features:**  
- **High Efficiency:** Quasi-resonant switching reduces switching losses.  
- **Low Standby Power:** <30 mW in no-load conditions.  
- **Integrated Protections:** OVP, OCP, OTP, and brown-in/out protection.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Soft Start:** Prevents inrush current during startup.  
- **HV Startup:** Integrated high-voltage startup eliminates the need for an external circuit.  

The TEA1761T is commonly used in adapters, chargers, and auxiliary power supplies.
