Description and Introduction

1.25A High Efficiency Switching Regulator The LT1072IN8 is a switching regulator IC 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 (depends on configuration)  
- **Output Current:** Up to 1.25A (switch current limit)  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 90% (depending on configuration)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The LT1072IN8 is a step-down (buck), step-up (boost), or flyback switching regulator.  
- It includes an onboard switch, oscillator, and control circuitry, reducing external component count.  
- Designed for high efficiency in battery-powered and industrial applications.  

### **Features:**  
- **Wide Input Voltage Range (3V–60V)** – Suitable for automotive and industrial applications.  
- **Internal Current Limit (1.25A)** – Protects against overloads.  
- **Low Quiescent Current (6mA typical)** – Improves efficiency at light loads.  
- **Adjustable Output Voltage** – Configurable via external resistors.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Single Inductor Operation** – Simplifies design for buck, boost, or flyback topologies.  

This information is based on the manufacturer's datasheet. For detailed application circuits and performance graphs, refer to official documentation.

Description and Introduction

1.25A High Efficiency Switching Regulator The LT1072IN8 is a 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:** 3V to 60V  
- **Output Voltage Range:** Adjustable from 1.25V to 40V  
- **Output Current:** Up to 1.25A  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Topology:** Buck, Boost, Flyback, or Inverting  

### **Descriptions:**  
The LT1072IN8 is a monolithic, high-efficiency switching regulator designed for step-down (buck), step-up (boost), and voltage-inverting applications. It integrates a power switch, oscillator, and control circuitry, simplifying power supply design. The device operates over a wide input voltage range and provides high efficiency with minimal external components.  

### **Features:**  
- **Wide Input Voltage Range (3V to 60V)**  
- **1.25A Output Current Capability**  
- **Built-In Power Switch (1.5A, 65V)**  
- **Low Quiescent Current (6mA typical)**  
- **Adjustable Output Voltage (1.25V to 40V)**  
- **Frequency Compensation Included**  
- **Thermal Shutdown Protection**  
- **Short-Circuit Protection**  
- **Suitable for Buck, Boost, Flyback, and Inverting Configurations**
