Description and Introduction

2-Phase, 5-Bit VID, Current Mode, High Efficiency, Synchronous Step-Down Switching Regulator The LTC1709EG-85#TR is a high-efficiency, dual-phase synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage:** Adjustable down to 0.8V  
- **Operating Frequency:** 550kHz (per phase)  
- **Output Current:** Up to 30A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Package:** 28-Lead SSOP  
- **Operating Temperature Range:** -40°C to 85°C  
- **Features:**  
  - Dual-phase operation for reduced input/output ripple  
  - Adjustable current limit  
  - Programmable soft-start  
  - Overvoltage and undervoltage protection  
  - Differential remote sensing  

### **Descriptions and Features:**  
- The LTC1709EG-85#TR is designed for high-current, low-voltage applications such as microprocessors, ASICs, and FPGAs.  
- It uses a constant-frequency current-mode architecture for stable operation.  
- The dual-phase design improves efficiency and reduces thermal stress.  
- Includes fault protection features like overcurrent and overtemperature shutdown.  
- Supports external synchronization for noise-sensitive applications.  

This regulator is ideal for high-performance power supply designs requiring precise voltage regulation and high efficiency.
