Description and Introduction

No Rsense, Low EMI, Synchronous DC/DC Controller The LTC3809EDD is a high-efficiency, current-mode synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Output Voltage Range:** 0.8V to 60V  
- **Switching Frequency:** Programmable from 50kHz to 1MHz  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** DFN-10 (3mm x 3mm)  
- **Topology:** Synchronous Buck  
- **Current Sense:** External Sense Resistor  
- **Efficiency:** Up to 95%  

### **Descriptions:**  
The LTC3809EDD is designed for high-voltage, high-efficiency DC/DC conversion applications. It features a current-mode architecture for fast transient response and stable operation. The device supports a wide input voltage range and can operate in dropout conditions with 100% duty cycle.  

### **Features:**  
- Wide input voltage range (4V to 60V)  
- Programmable switching frequency (50kHz to 1MHz)  
- Adjustable output voltage (0.8V to 60V)  
- Synchronous rectification for high efficiency  
- External frequency synchronization capability  
- Low shutdown current (<1μA)  
- Soft-start functionality  
- Current-mode control for improved transient response  
- Overcurrent and thermal protection  

This information is based on the manufacturer's datasheet and technical documentation.
