Description and Introduction

2-Phase, 5-Bit VID, Current Mode, High Efficiency, Synchronous Step-Down Switching Regulator The LTC1709EG-85#PBF 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  
- **Output Current:** Up to 25A per phase (50A total with two phases)  
- **Switching Frequency:** 550kHz (per phase)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 28-Lead SSOP  

### **Descriptions:**  
- Dual-phase operation reduces input and output ripple current.  
- Uses a constant-frequency current-mode architecture.  
- Features adjustable current limit and soft-start.  
- Supports pre-biased outputs.  
- Includes power-good indicator and tracking capability.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input/output capacitance requirements.  
- **High Efficiency:** Minimizes power loss with synchronous rectification.  
- **Wide Input Voltage Range:** Suitable for various power sources.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Current-Mode Control:** Ensures fast transient response.  
- **Programmable Soft-Start:** Prevents inrush current at startup.  
- **Power-Good Output:** Monitors output voltage status.  
- **Thermal Protection:** Prevents overheating.  

This regulator is commonly used in high-performance computing, telecom, and industrial applications requiring high current and efficiency.
