Description and Introduction

Fast No RSENSE Step-Down Synchronous Controller with Margining, Tracking and PLL The LTC3770EUH#PBF is a high-performance synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.8V to 24V  
- **Switching Frequency:** Adjustable from 50kHz to 900kHz  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 32-Lead QFN (5mm × 5mm)  
- **Topology:** Synchronous Buck Controller  
- **Efficiency:** Up to 98%  
- **Current Mode Control:** Yes  
- **Phase-Lockable Frequency:** Yes  

### **Descriptions:**  
The LTC3770EUH#PBF is designed to drive N-channel MOSFETs in a synchronous step-down converter configuration. It features a constant-frequency current-mode architecture for stable operation and fast transient response. The device includes adjustable soft-start, overcurrent protection, and a wide input voltage range, making it suitable for high-power applications.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 38V)**  
- **High Efficiency (Up to 98%)**  
- **Adjustable Frequency (50kHz to 900kHz)**  
- **Phase-Lockable for Noise-Sensitive Applications**  
- **Programmable Soft-Start**  
- **Precision 0.8V Reference Voltage**  
- **Current Mode Control for Excellent Line and Load Regulation**  
- **Low Shutdown Current (<1μA)**  
- **Overcurrent Protection with Foldback**  

This regulator is commonly used in industrial, automotive, and telecom applications requiring high efficiency and precise voltage regulation.
