Description and Introduction

High Input Voltage, Current Mode Boost, Flyback and SEPIC Controller The LTC1871IMS-7 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:** 0.8V to (VIN - 2V)  
- **Switching Frequency:** Adjustable (100kHz to 500kHz)  
- **Maximum Duty Cycle:** 98%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 10-Lead MSOP  
- **Efficiency:** Up to 95%  
- **Current Limit:** Adjustable  

### **Descriptions:**  
The LTC1871IMS-7 is designed for high-efficiency step-down DC/DC conversion, capable of driving N-channel MOSFETs. It operates in a constant-frequency current-mode architecture, providing excellent transient response and loop stability.  

### **Features:**  
- **Wide Input Voltage Range (4V to 60V)**  
- **Adjustable Output Voltage (0.8V to VIN - 2V)**  
- **Programmable Frequency (100kHz to 500kHz)**  
- **Low Quiescent Current (50µA in Shutdown)**  
- **Synchronous Operation for High Efficiency**  
- **Adjustable Soft-Start**  
- **Thermal Shutdown Protection**  
- **Current Mode Control for Fast Transient Response**  

This regulator is suitable for applications requiring high efficiency and wide input voltage ranges, such as industrial, automotive, and telecom power supplies.
