Description and Introduction

Wide Input Range, No RSENSE Current Mode Boost, Flyback and SEPIC Controller The LTC1871IMS#PBF is a high-efficiency, current-mode synchronous step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Maximum Output Current:** Up to 6A  
- **Switching Frequency:** Adjustable (100kHz to 500kHz)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead MSOP  

### **Descriptions:**  
The LTC1871IMS#PBF is a synchronous buck converter with an integrated high-side and low-side MOSFET driver. It operates in current-mode control for fast transient response and stable operation. The device is designed for high-efficiency power conversion in applications requiring a wide input voltage range.  

### **Features:**  
- **Synchronous Operation:** Reduces power loss by replacing the external Schottky diode with an internal MOSFET.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Low Quiescent Current:** 60µA in shutdown mode.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent and Thermal Protection:** Enhances reliability.  
- **Current-Mode Control:** Improves loop stability and transient response.  

This regulator is suitable for industrial, automotive, and telecom applications requiring high efficiency and compact power solutions.
