Description and Introduction

Constant Frequency Current Mode Step-Down DC/DC Controller in SOT-23 The LTC1772CS6#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 5V (adjustable)  
- **Maximum Output Current:** 3A  
- **Switching Frequency:** 550kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
The LTC1772CS6#PBF is a synchronous buck regulator designed for high efficiency and compact power supply solutions. It integrates a high-side P-channel MOSFET and a synchronous N-channel MOSFET, reducing external component count. The device operates in continuous conduction mode (CCM) for improved efficiency and includes features like soft-start and frequency synchronization.  

### **Features:**  
- **Synchronous Operation:** Reduces power loss and improves efficiency.  
- **Low Quiescent Current:** 40µA in shutdown mode.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Internal Soft-Start:** Prevents inrush current.  
- **Frequency Synchronization:** Allows synchronization to an external clock.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Short-Circuit Protection:** Enhances reliability.  

This regulator is suitable for applications requiring high efficiency in a small footprint, such as portable devices, industrial systems, and distributed power supplies.
