Description and Introduction

Dual Synchronous 1.5A/1A 4MHz Step-Down DC/DC Regulator The LTC3417AEDHC is a high-efficiency, monolithic synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.25V to 5.5V  
- **Output Voltage Range:** 0.6V to VIN  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 1MHz or 2.25MHz (selectable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 16-Lead DFN (5mm × 3mm × 0.75mm)  
- **Features:**  
  - Burst Mode® operation for improved light-load efficiency  
  - Adjustable soft-start  
  - Power good output  
  - Internal synchronous rectification  
  - Low dropout operation  
  - Overcurrent and overtemperature protection  

### **Descriptions and Features:**  
The LTC3417AEDHC is designed for high-performance applications requiring high efficiency and compact power solutions. It operates in either forced continuous mode or Burst Mode® operation, optimizing efficiency across load conditions. The adjustable switching frequency allows flexibility in noise-sensitive applications. The device includes internal compensation, reducing external component count.  

Key features include:  
- **Synchronous Operation:** Reduces power loss and improves efficiency.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Small Footprint:** Ideal for space-constrained designs.  

This converter is suitable for applications such as portable devices, industrial systems, and distributed power supplies.
