Description and Introduction

Dual Transistor Synchronous Forward Controller The LT1681ESW#TR is a high-speed, high-voltage, synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Output Voltage Range:** Adjustable down to 1.25V  
- **Switching Frequency:** Up to 200kHz  
- **Peak Output Current:** Up to 10A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**  
The LT1681ESW#TR is designed for high-power step-down (buck) converter applications. It drives external N-channel MOSFETs and features adaptive shoot-through protection to minimize switching losses. The device includes a precision reference, error amplifier, and oscillator for stable operation.  

### **Features:**  
- **Wide Input Voltage Range (4V to 60V)**  
- **Synchronous Operation for High Efficiency**  
- **Adjustable Output Voltage**  
- **Adaptive Shoot-Through Protection**  
- **Programmable Soft-Start**  
- **Current Mode Control for Fast Transient Response**  
- **Thermal Shutdown Protection**  
- **Under-Voltage Lockout (UVLO)**  

This regulator is suitable for industrial, automotive, and telecom applications requiring high efficiency and robust performance.
