Description and Introduction

Constant Frequency Current Mode Step-Down DC/DC Controller in SOT-23 The LTC1772IS6#PBF 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 VIN  
- **Maximum Output Current:** 1.5A  
- **Switching Frequency:** 550kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
- The LTC1772IS6#PBF is a monolithic synchronous buck regulator with an internal power switch.  
- It operates in continuous conduction mode (CCM) for improved efficiency.  
- Features a low dropout design, allowing the output to remain in regulation even when the input voltage approaches the output voltage.  
- Includes soft-start and frequency synchronization capabilities.  

### **Features:**  
- **High Efficiency Synchronous Operation**  
- **Low Quiescent Current (100μA in Burst Mode®)**  
- **Adjustable Output Voltage**  
- **Short-Circuit Protection**  
- **Thermal Shutdown Protection**  
- **Synchronizable Switching Frequency**  
- **Burst Mode Operation for Improved Light Load Efficiency**  

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