Description and Introduction

High Efficiency Step-Down and Inverting DC/DC Converter The LTC1174HVCN8-5 is a high-efficiency, step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Output Voltage:** Fixed 5V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 100kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead PDIP  

### **Descriptions:**  
The LTC1174HVCN8-5 is a high-voltage, low-power switching regulator designed for step-down (buck) conversion. It integrates a high-side power switch and control circuitry, requiring minimal external components.  

### **Features:**  
- **Wide Input Range:** Supports 4V to 60V input.  
- **Fixed 5V Output:** No external feedback resistors needed.  
- **Low Quiescent Current:** 120µA typical.  
- **Internal Power Switch:** Reduces external component count.  
- **Short-Circuit Protection:** Improves reliability.  
- **Thermal Shutdown:** Prevents overheating.  
- **Soft-Start:** Reduces inrush current.  

This part is suitable for automotive, industrial, and battery-powered applications requiring a stable 5V supply from high-voltage sources.
