Partnumber Manufacturer Quantity Availability
LTC3409EDD LINEAR 28 In Stock

Description and Introduction

600mA Low Vin Buck Regulator in 3mm x 3mm DFN The LTC3409EDD is a high-efficiency, synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** 0.6V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.5MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** DFN-8 (3mm × 3mm)  
- **Low Quiescent Current:** 25μA (typical)  
- **Features:**  
  - Burst Mode® operation for improved light-load efficiency  
  - Internal synchronous rectification  
  - Short-circuit protection  
  - Thermal shutdown  
  - 100% duty cycle capability  

### **Descriptions and Features:**  
The LTC3409EDD is designed for portable applications requiring high efficiency and compact size. It uses a constant-frequency, current-mode architecture for stable operation and fast transient response. The Burst Mode operation enhances efficiency at light loads, extending battery life. The device includes internal power switches, eliminating the need for external Schottky diodes.  

The DFN-8 package provides a small footprint, making it suitable for space-constrained designs. It is commonly used in handheld devices, portable instruments, and wireless applications.
