Description and Introduction

Low IQ, Dual, 2-Phase Synchronous Step-Down Controller The LTC3827IUH#PBF is a high-performance synchronous step-down DC/DC controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.8V to 5.5V  
- **Switching Frequency:** 50kHz to 900kHz (adjustable)  
- **Maximum Output Current:** Up to 20A (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 32-Lead QFN (5mm x 5mm)  
- **Control Method:** Constant-frequency current mode  

### **Descriptions:**  
The LTC3827IUH#PBF is designed for high-efficiency step-down power conversion, offering precise output voltage regulation. It features a constant-frequency current-mode architecture for stable operation and fast transient response. The device supports adjustable switching frequency and includes features like soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Wide Input Voltage Range:** 4.5V to 38V  
- **Adjustable Output Voltage (0.8V to 5.5V)**  
- **Programmable Switching Frequency (50kHz to 900kHz)**  
- **Current-Mode Control for Fast Transient Response**  
- **Integrated MOSFET Drivers**  
- **Adjustable Soft-Start**  
- **Overcurrent and Thermal Protection**  
- **Low Shutdown Current (<1µA)**  
- **Synchronizable to External Clock**
