Description and Introduction

3-Phase, 600kHz, Synchronous Buck Switching Regulator Controller The LTC3731HG is a high-performance synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Switching Frequency:** 50kHz to 600kHz (programmable)  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 36-Lead SSOP (HG Package)  

### **Descriptions:**  
- The LTC3731HG is a dual-phase, synchronous step-down DC/DC controller designed for high-efficiency power conversion.  
- It features adaptive voltage positioning (AVP) to improve transient response.  
- The device supports multi-phase operation for high-current applications.  
- It includes a precision reference and error amplifier for accurate output regulation.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input and output ripple current.  
- **Adaptive Voltage Positioning (AVP):** Optimizes transient response.  
- **Programmable Frequency:** Allows optimization for efficiency or component size.  
- **Current Mode Control:** Ensures stable operation with fast transient response.  
- **Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Low Shutdown Current:** <10µA when disabled.
