Description and Introduction

Dual Synchronous 1.4A/800mA 4MHz Step-Down DC/DC Regulator The LTC3417EDHC#PBF is a high-efficiency, monolithic synchronous buck regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.25V to 5.5V  
- **Output Voltage Range:** 0.6V to 5V (adjustable via external resistors)  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead DFN (5mm × 3mm × 0.75mm)  

### **Descriptions:**
- The LTC3417EDHC#PBF is a synchronous step-down DC/DC converter with an integrated power switch, designed for high efficiency and compact power solutions.  
- It operates in a constant-frequency, current-mode architecture, providing fast transient response and stable operation.  
- The device includes internal soft-start, overcurrent protection, and thermal shutdown for enhanced reliability.  

### **Features:**
- **High Efficiency:** Uses low RDS(ON) internal switches to minimize power loss.  
- **Low Dropout Operation:** Allows 100% duty cycle for extended battery life.  
- **Programmable Frequency:** Fixed 1MHz operation reduces external component size.  
- **Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Synchronizable:** Can be synchronized to an external clock.  
- **Low Quiescent Current:** 40μA in shutdown mode for power savings.  
- **Thermal Shutdown:** Protects the IC from overheating.  

This regulator is commonly used in portable electronics, industrial applications, and distributed power systems.
