Description and Introduction

250kHz Low Supply Current High Efficiency 1.5A Switching Regulator The LT1373HVCS8#PBF is a high voltage, high efficiency switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 3.5V to 30V (up to 60V with external components)  
- **Output Voltage Range:** Adjustable from 1.24V to 30V  
- **Output Current:** Up to 3A (switch current limit)  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC (SO-8)  

### **Descriptions:**  
The LT1373HVCS8#PBF is a high voltage, current mode step-down (buck) switching regulator. It is designed for high efficiency power conversion in applications requiring wide input voltage ranges. The device includes an onboard NPN power switch, oscillator, control circuitry, and protection features.  

### **Features:**  
- **High Voltage Operation:** Supports input voltages up to 30V (60V with external components).  
- **Current Mode Control:** Improves transient response and loop stability.  
- **Low Dropout Operation:** Allows duty cycles up to 100%.  
- **Built-in Protection:** Includes thermal shutdown, current limiting, and soft-start.  
- **Adjustable Output:** Uses an external resistor divider for flexible output voltage setting.  
- **Low Quiescent Current:** 5mA typical when operating.  
- **Wide Temperature Range:** Suitable for industrial and automotive applications.  

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