Description and Introduction

High Efficiency Synchronous Step-Down Switching Regulators The LTC1148HVCS#TR is a high-efficiency, high-voltage synchronous step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 8V to 48V  
- **Output Voltage Range:** Adjustable from 3.3V to 50V  
- **Output Current:** Up to 5A  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead SOIC (Narrow)  
- **Features Burst Mode® Operation** for improved light-load efficiency  

### **Descriptions and Features:**  
- **High Voltage Operation:** Supports input voltages up to 48V.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Burst Mode Operation:** Enhances efficiency at light loads.  
- **Current Mode Control:** Ensures stable operation and fast transient response.  
- **Short-Circuit Protection:** Includes foldback current limiting.  
- **Low Quiescent Current:** Typically 1.2mA in Burst Mode.  
- **Thermal Shutdown:** Protects the device from overheating.  

This regulator is suitable for industrial, automotive, and telecom applications requiring high efficiency and high-voltage step-down conversion.
