Description and Introduction

15碌A Quiescent Current 1.5A Monolithic Synchronous Step-Down Regulator The LTC1875EGN is a high-efficiency, monolithic 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 0.8V  
- **Switching Frequency:** Programmable from 50kHz to 500kHz  
- **Maximum Duty Cycle:** 98%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 16-Lead SSOP  

### **Descriptions:**  
The LTC1875EGN is designed to drive N-channel MOSFETs in a synchronous buck converter topology. It features a constant-frequency current-mode architecture for stable operation and fast transient response.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification  
- **Programmable Frequency:** Adjustable via an external resistor  
- **Low Quiescent Current:** 150µA in shutdown mode  
- **Soft-Start:** Reduces inrush current during startup  
- **Wide Input Range:** Supports 4V to 60V operation  
- **Current Mode Control:** Ensures stable loop response  
- **Short-Circuit Protection:** Prevents damage under fault conditions  

The LTC1875EGN is suitable for applications such as industrial power supplies, automotive systems, and distributed power architectures.
