Description and Introduction

Dual Synchronous 1.4A/800mA 4MHz Step-Down DC/DC Regulator The LTC3417 is a high efficiency, monolithic synchronous buck regulator manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.25V to 5.5V  
- **Output Voltage Range:** 0.6V to 5V (adjustable via external resistors)  
- **Maximum Output Current:** 4A  
- **Switching Frequency:** 1.25MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 40µA (in Burst Mode operation)  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  

### **Descriptions:**  
- The LTC3417 is a synchronous step-down DC/DC converter optimized for high efficiency and compact power solutions.  
- It uses a constant-frequency, current-mode architecture for stable operation.  
- The device includes internal power switches, reducing the need for external components.  
- It supports Burst Mode operation for improved efficiency at light loads.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Burst Mode Operation:** Enhances light-load efficiency.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  
- **Power Good Output:** Provides a signal indicating output voltage regulation.  
- **Thermal Shutdown:** Protects the device from overheating.
