Description and Introduction

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

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage:** Adjustable down to 0.8V  
- **Switching Frequency:** 550kHz  
- **Maximum Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 28-Lead SSOP  

### **Descriptions:**  
The LTC1709EG-85 is designed for high-current, high-efficiency applications. It uses a synchronous rectification architecture to minimize power loss and improve efficiency. The controller drives external N-channel MOSFETs and includes features like adjustable current limiting, soft-start, and thermal shutdown.  

### **Features:**  
- **Synchronous Operation:** Reduces power loss by replacing the Schottky diode with a MOSFET.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Current Mode Control:** Ensures fast transient response and stable operation.  
- **Programmable Soft-Start:** Limits inrush current during startup.  
- **Overcurrent and Overtemperature Protection:** Enhances system reliability.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Description and Introduction

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

### **Descriptions:**  
The LTC1709EG-85 is designed for high-current applications, providing precise voltage regulation with minimal external components. It features dual-phase operation to reduce input and output ripple current, improving efficiency and thermal performance.  

### **Features:**  
- Dual-phase operation for reduced input/output ripple  
- Adjustable switching frequency (up to 550kHz per phase)  
- Precision 0.8V reference (±1.5% over temperature)  
- Programmable soft-start  
- Overcurrent and overtemperature protection  
- Differential remote sensing for accurate output regulation  
- Low shutdown current (<100μA)
