Description and Introduction

GreenChip synchronous rectifier controller The TEA1795T is a GreenChip synchronous rectifier (SR) controller IC manufactured by NXP Semiconductors. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** NXP Semiconductors  
- **Type:** Synchronous Rectifier (SR) Controller  
- **Package:** SO8 (8-pin Small Outline package)  
- **Operating Voltage Range:** 4.5 V to 38 V  
- **Maximum Switching Frequency:** 1 MHz  
- **Operating Temperature Range:** -40°C to +150°C  
- **Low Quiescent Current:** Typically 100 µA  

### **Descriptions:**
The TEA1795T is designed for high-efficiency power supplies, particularly in flyback and resonant converter topologies. It replaces traditional diode rectifiers with MOSFETs to minimize conduction losses, improving overall system efficiency.  

### **Features:**
- **Adaptive Gate Drive Timing:** Ensures optimal MOSFET switching for efficiency.  
- **High-Side and Low-Side SR Control:** Supports both configurations.  
- **Fast Turn-Off Detection:** Prevents reverse current flow.  
- **Integrated Bootstrap Diode:** Simplifies external circuitry.  
- **Overvoltage Protection (OVP):** Safeguards against excessive voltages.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Compatible with DCM, CCM, and QR Modes:** Works in discontinuous, continuous, and quasi-resonant operation.  

This IC is commonly used in AC/DC adapters, LED drivers, and other high-efficiency power supply applications.
