Description and Introduction

High Voltage, Current Mode Switching Regulator Controller with Programmable Operating Frequency The LT3844EFE#PBF is a high voltage, current mode step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable from 50kHz to 500kHz  
- **Peak Current Sense Threshold:** 75mV  
- **Maximum Duty Cycle:** 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  
- **Topology:** Synchronous Buck Controller  

### **Descriptions:**  
The LT3844EFE#PBF is designed for high efficiency step-down DC/DC conversion in applications requiring high input voltages. It features a current mode control architecture for fast transient response and stable operation. The controller supports synchronous rectification for improved efficiency and can be used with external N-channel MOSFETs.  

### **Features:**  
- **Wide Input Voltage Range (4V to 60V)**  
- **Adjustable Output Voltage (Down to 0.8V)**  
- **Programmable Frequency (50kHz to 500kHz)**  
- **Synchronous Rectification for High Efficiency**  
- **Low Shutdown Current (<1µA)**  
- **Adjustable Soft-Start**  
- **Cycle-by-Cycle Current Limit**  
- **Thermal Shutdown Protection**  
- **16-Lead TSSOP Package with Exposed Pad**  

This controller is suitable for industrial, automotive, and telecom applications requiring high voltage step-down conversion.
