Description and Introduction

Constant Frequency Current Mode Step-Down DC/DC Controller in SOT-23 The LTC1772CS6#TRMPBF is a high-efficiency synchronous step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** 0.8V to 36V (adjustable via external resistors)  
- **Maximum Output Current:** 3A  
- **Switching Frequency:** 200kHz to 500kHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
- The LTC1772 is a synchronous buck converter with an integrated N-channel MOSFET switch and synchronous rectifier.  
- It features a constant-frequency current-mode architecture for stable operation.  
- Includes soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4V to 36V input.  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  
- **Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  

This regulator is commonly used in industrial, automotive, and telecom applications requiring high efficiency and compact design.
