Description and Introduction

1.25A High Efficiency Switching Regulator The LT1072 is a monolithic switching regulator designed by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features of the LT1072:

### **Specifications:**  
- **Input Voltage Range:** 3V to 60V  
- **Output Voltage Range:** Adjustable from 1.24V to 50V  
- **Output Current:** Up to 1.25A  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** TO-220, TO-3, DIP-8  

### **Descriptions:**  
- The LT1072 is a step-down (buck), step-up (boost), or inverting switching regulator.  
- It includes an onboard oscillator, switch driver, and error amplifier.  
- Designed for high-efficiency power conversion with minimal external components.  
- Suitable for battery-powered applications, automotive systems, and industrial power supplies.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 3V to 60V input.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **High Efficiency:** Minimizes power loss with synchronous rectification capability.  
- **Current Limiting:** Built-in protection against overcurrent conditions.  
- **Thermal Shutdown:** Prevents damage due to overheating.  
- **Low Dropout Operation:** Maintains regulation even with small input-output differentials.  
- **Soft-Start Capability:** Reduces inrush current during startup.  

The LT1072 is optimized for compact and efficient power supply designs. For detailed application circuits, refer to the datasheet.
