### **Specifications:**  
- **Input Voltage Range:** 3.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 30V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** TO-220, DD, and surface-mount packages  

### **Descriptions:**  
The LT1373 is a step-down (buck) switching regulator designed for high efficiency power conversion. It integrates a high-performance switch, oscillator, and control circuitry. The device is suitable for battery-powered and industrial applications requiring high efficiency and compact design.  

### **Features:**  
- **High Efficiency:** Minimizes power loss with synchronous rectification.  
- **Wide Input Range:** Supports operation from 3.5V to 30V.  
- **Adjustable Output:** Can be set via an external resistor divider.  
- **Current Mode Control:** Ensures stable operation under varying loads.  
- **Short-Circuit Protection:** Includes cycle-by-cycle current limiting.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  

This information is based on the manufacturer's datasheet and technical documentation.
