Description and Introduction

100kHz, 5A, 2.5A and 1.25A High Efficiency Switching Regulators The LT1170 is a 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:** 3V to 60V  
- **Output Voltage Range:** Adjustable from 1.25V to 50V  
- **Output Current:** Up to 2.5A (with external components)  
- **Switching Frequency:** 100kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** TO-220, TO-3, and DD (DIP) packages  

### **Descriptions:**  
- The LT1170 is a monolithic, high power, step-down (buck) switching regulator.  
- It includes an onboard power switch, oscillator, and control circuitry.  
- Designed for simplicity, it requires minimal external components for operation.  
- Suitable for battery-powered applications, automotive systems, and industrial power supplies.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 3V to 60V.  
- **High Efficiency:** Reduces power dissipation with synchronous rectification.  
- **Adjustable Output:** Can be set using external resistors.  
- **Current Limiting:** Built-in protection against overloads.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  
- **Thermal Shutdown:** Prevents damage from overheating.  

This information is based solely on the LT1170's datasheet from Linear Technology.
