Description and Introduction

Dual Monolithic 600mA Synchronous Step-Down Regulator The **LTC3419EDD-1#PBF** is a high-efficiency, 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:** 4MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)

### **Descriptions:**  
The LTC3419EDD-1#PBF is a high-performance monolithic synchronous buck regulator designed for high-efficiency power conversion in space-constrained applications. It operates at a fixed 4MHz switching frequency, allowing the use of small external components. The device features **Burst Mode® operation**, which minimizes quiescent current during light loads, improving efficiency.  

### **Features:**  
- **High Efficiency Synchronous Operation**  
- **4MHz Constant Switching Frequency**  
- **Burst Mode Operation for Improved Light-Load Efficiency**  
- **Low Quiescent Current (40µA in Burst Mode)**  
- **Internal Soft-Start**  
- **Short-Circuit Protection**  
- **Thermal Shutdown Protection**  
- **100% Duty Cycle for Low Dropout**  
- **Small 10-Lead DFN Package**  

This converter is suitable for applications such as **portable devices, DSP/FPGA power supplies, and battery-powered systems**.
