Description and Introduction

PolyPhase, Synchronous Step-Down Switching Regulator The LTC3729LEUH-6 is a PolyPhase synchronous buck switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage Range:** 0.6V to 5.5V  
- **Switching Frequency:** 300kHz per phase (adjustable)  
- **Number of Phases:** 2 (supports PolyPhase operation)  
- **Maximum Duty Cycle:** 100%  
- **Current Mode Control:** Yes  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 32-Lead QFN (5mm x 5mm)  

### **Descriptions:**  
The LTC3729LEUH-6 is designed for high-efficiency, high-current DC/DC conversion applications. It features PolyPhase operation, which reduces input and output ripple current while improving thermal performance. The controller uses current-mode control for fast transient response and includes programmable current sharing for balanced load distribution.  

### **Features:**  
- **PolyPhase Operation:** Reduces input/output ripple and component stress  
- **Adjustable Frequency:** 150kHz to 600kHz per phase  
- **Precision Reference:** ±1% over temperature  
- **Differential Remote Sensing:** Ensures accurate output voltage regulation  
- **Programmable Soft-Start:** Reduces inrush current  
- **Overcurrent Protection:** Cycle-by-cycle current limiting  
- **Thermal Shutdown:** Protects against overheating  
- **Power Good Output:** Monitors output voltage status  

For detailed application information, refer to the official datasheet from Analog Devices.
