Description and Introduction

Dual, 2-Phase Step-Down Controller with Tracking The LTC3828EG#PBF is a high-performance synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Switching Frequency:** 50kHz to 900kHz (programmable)  
- **Maximum Duty Cycle:** 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 20-Lead SSOP  
- **Topology:** Synchronous Buck Controller  
- **Efficiency:** Up to 95%  
- **Current Limit:** Adjustable  

### **Descriptions:**  
The LTC3828EG#PBF is designed for high-efficiency step-down DC/DC conversion. It drives external N-channel MOSFETs and operates in either continuous or discontinuous conduction mode. It features a constant-frequency current-mode architecture for stable operation across a wide input voltage range.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 38V)**  
- **Programmable Frequency (50kHz to 900kHz)**  
- **Adjustable Output Voltage (0.8V to 5.5V)**  
- **Low Dropout Operation (95% Duty Cycle)**  
- **Precision 0.8V Reference (±1.5%)**  
- **Adjustable Soft-Start**  
- **Power Good Output**  
- **Overcurrent and Overtemperature Protection**  
- **Synchronous Operation for High Efficiency**  

This controller is suitable for applications such as telecom, industrial power supplies, and distributed power systems.
