Description and Introduction

250kHz Low Supply Current High Efficiency 1.5A Switching Regulator The LT1373HVCS8#TR is a high voltage, high efficiency switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 3.5V to 30V (40V max for HV version)  
- **Output Voltage Range:** Adjustable from 1.25V to 30V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
- The LT1373HVCS8#TR is a current-mode switching regulator with an integrated high-side switch.  
- It is designed for high efficiency step-down (buck) applications.  
- The device includes built-in protection features such as thermal shutdown and current limiting.  
- It operates at a fixed 500kHz switching frequency, reducing external component size.  

### **Features:**  
- **High Voltage Operation:** Supports input voltages up to 40V (HV version).  
- **High Efficiency:** Minimizes power loss with synchronous rectification.  
- **Adjustable Output:** Feedback pin allows flexible output voltage setting.  
- **Current Mode Control:** Ensures stable operation with fast transient response.  
- **Built-in Protection:** Includes thermal shutdown and current limit.  
- **Low Dropout Operation:** Maintains regulation even when input voltage approaches output voltage.  

This regulator is suitable for industrial, automotive, and power supply applications requiring high efficiency and high voltage operation.
