Description and Introduction

Constant Frequency Current Mode Step-Down DC/DC Controller in SOT-23 The LTC1772BIS6#PBF is a high-efficiency, monolithic 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)  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 550kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
- The LTC1772BIS6#PBF is a synchronous buck converter with an integrated power switch, reducing external component count.  
- It features Burst Mode® operation for improved efficiency at light loads.  
- The device includes internal soft-start and current limiting for protection.  

### **Features:**  
- **Synchronous Operation:** Improves efficiency by reducing power loss.  
- **Burst Mode® Operation:** Enhances light-load efficiency.  
- **Low Dropout Operation:** Allows 100% duty cycle for low input-output differentials.  
- **Short-Circuit Protection:** Includes cycle-by-cycle current limiting.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Thermal Shutdown:** Prevents overheating.  

This regulator is suitable for applications such as industrial power supplies, automotive systems, and distributed power architectures.
