Description and Introduction

Wide Input Range, No RSENSE Current Mode Boost, Flyback and SEPIC Controller The LTC1871EMS-1#PBF is a high-efficiency, monolithic synchronous step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** 0.8V to VIN  
- **Maximum Output Current:** Up to 10A (depending on external components)  
- **Switching Frequency:** Adjustable from 50kHz to 500kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead MSOP  
- **Control Method:** Current-mode PWM  
- **Synchronous Rectification:** Yes (integrated N-channel MOSFETs)  
- **Low Quiescent Current:** 1.5mA (typical)  
- **Protection Features:** Overcurrent, overtemperature, and undervoltage lockout  

### **Descriptions:**  
The LTC1871EMS-1#PBF is designed for high-power applications requiring efficient step-down conversion. It integrates synchronous rectification to minimize power loss and improve efficiency. The device operates in current-mode control for fast transient response and stable operation.  

### **Features:**  
- **Wide Input Voltage Range (4V to 36V)**  
- **High Efficiency (up to 95%)**  
- **Adjustable Switching Frequency (50kHz–500kHz)**  
- **Integrated Power MOSFETs**  
- **Low Dropout Operation (100% Duty Cycle Capable)**  
- **Programmable Soft-Start**  
- **Synchronizable to External Clock**  
- **Thermal Shutdown Protection**  
- **Available in Compact MSOP Package**  

This regulator is suitable for applications such as industrial power supplies, telecom systems, automotive electronics, and battery-powered devices.
