Description and Introduction

High Power Synchronous Switching Regulator Controller for DDR Memory Termination The LTC3831EGN#TRPBF is a high-efficiency, dual-phase 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:** Adjustable from 200kHz to 600kHz  
- **Maximum Output Current:** Up to 25A per phase (50A total with two phases)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 20-Lead SSOP  

### **Descriptions:**  
- The LTC3831 is a dual-phase, synchronous step-down switching regulator controller designed for high-current applications.  
- It uses a constant-frequency current-mode architecture for precise regulation and fast transient response.  
- The device supports multi-phase operation to reduce input and output ripple while improving thermal performance.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input/output capacitance and improves efficiency.  
- **Programmable Frequency:** Adjustable from 200kHz to 600kHz.  
- **Current-Mode Control:** Ensures stable operation and fast transient response.  
- **Power Good Output:** Monitors output voltage status.  
- **External Synchronization:** Allows synchronization to an external clock.  
- **Soft-Start:** Programmable to minimize inrush current.  
- **Low Shutdown Current:** <1μA when disabled.
