Description and Introduction

Dual Monolithic 600mA Synchronous Step-Down Regulator The LTC3419EDD is a high efficiency, monolithic synchronous buck regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.25V to 5.5V  
- **Output Voltage Range:** 0.8V to 5V (adjustable)  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 1.5MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  

### **Descriptions:**  
The LTC3419EDD is designed for high-performance power management in portable and battery-powered applications. It features a synchronous rectification architecture for improved efficiency and reduced power loss.  

### **Features:**  
- **Synchronous Operation:** Improves efficiency by reducing conduction losses.  
- **Burst Mode® Operation:** Enhances light-load efficiency.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Short-Circuit Protection:** Safeguards against output faults.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  
- **Power Good Output:** Monitors output voltage status.  

This regulator is suitable for applications such as portable devices, DSP/FPGA power supplies, and distributed power systems.
