Description and Introduction

5.5V to 60V 1.5A/ 200kHz Step-Down Switching Regulator The LT1766IFE is a high efficiency, monolithic step-down switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 3.6V to 25V  
- **Output Voltage Range:** Adjustable from 1.21V to 20V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 90%  
- **Dropout Voltage:** 300mV (typical)  
- **Quiescent Current:** 30µA (typical) in shutdown mode  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP  

### **Descriptions:**  
- The LT1766IFE is a synchronous buck regulator with an integrated power switch, designed for high efficiency and low noise operation.  
- It features a low dropout design, allowing it to maintain regulation even when the input voltage is close to the output voltage.  
- The device includes internal soft-start and current limit protection for enhanced reliability.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Low Dropout Operation:** Maintains regulation with small input-output differentials.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Shutdown Mode:** Reduces quiescent current to 30µA.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load currents.  
- **Soft-Start Function:** Reduces inrush current during startup.  

The LT1766IFE is commonly used in battery-powered systems, industrial applications, and distributed power supplies where high efficiency and compact design are required.
