Description and Introduction

Dual, 550kHz, 2-Phase Synchronous Regulators The LTC3728LXCUH#TR is a PolyPhase 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 Range:** 0.8V to 5.5V  
- **Switching Frequency:** Adjustable (100kHz to 600kHz)  
- **Phase Configurations:** 2-Phase or 1-Phase operation  
- **Efficiency:** Up to 95%  
- **Current Mode Control:** Provides fast transient response  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 32-Lead (5mm × 5mm) QFN  

### **Descriptions:**  
The LTC3728LXCUH#TR is designed for high-efficiency, high-current step-down DC/DC conversion. It features PolyPhase operation, reducing input and output ripple currents while optimizing thermal performance. The controller supports both synchronous and non-synchronous rectification and includes adjustable current limiting and soft-start functionality.  

### **Features:**  
- **PolyPhase Operation:** Reduces input/output ripple and improves efficiency.  
- **Adjustable Switching Frequency:** 100kHz to 600kHz.  
- **Precision 0.8V Reference:** Allows low output voltages.  
- **Current Mode Control:** Ensures fast transient response.  
- **Programmable Soft-Start:** Prevents inrush current.  
- **Overcurrent Protection:** Adjustable current limit.  
- **Wide Input Range:** 4.5V to 36V.  
- **Thermal Protection:** Prevents overheating.  
- **32-Lead QFN Package:** Compact and thermally efficient.
