Description and Introduction

3-Phase, Single Output Synchronous Step-Down DC/DC Controller with Diffamp The LTC3829EUHF#PBF is a high-performance synchronous step-down DC/DC controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.6V to 5.5V  
- **Switching Frequency:** 50kHz to 900kHz (programmable)  
- **Maximum Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 38-Lead QFN (5mm × 7mm)  

### **Descriptions:**  
- The LTC3829EUHF#PBF is a high-efficiency, synchronous step-down switching regulator controller.  
- It drives external N-channel MOSFETs to deliver high-current, low-voltage outputs.  
- Features a constant-frequency current-mode architecture for stable operation.  
- Supports adjustable switching frequency for optimization of efficiency and component size.  

### **Features:**  
- **Wide Input Voltage Range:** 4.5V to 38V  
- **Programmable Frequency:** 50kHz to 900kHz  
- **Fast Transient Response:** Optimized for high-performance applications  
- **Precision Reference:** 0.6V ±1%  
- **Phase-Lockable Frequency:** Synchronizable to an external clock  
- **Programmable Soft-Start:** Reduces inrush current  
- **Overcurrent and Overtemperature Protection:** Enhances system reliability  
- **Low Shutdown Current:** <1μA  

This controller is commonly used in telecom, industrial, and automotive applications requiring high-efficiency power conversion.
