Description and Introduction

Constant Frequency Current Mode Step-Down DC/DC Controller in SOT-23 The LTC1772BIS6#TRPBF 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 (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
The LTC1772BIS6#TRPBF is a synchronous buck converter designed for high-efficiency step-down voltage regulation. It integrates both high-side and low-side MOSFETs, reducing external component count. The device operates in continuous conduction mode (CCM) for improved efficiency at higher loads.  

### **Features:**  
- **Synchronous Operation:** Reduces power loss and improves efficiency.  
- **Low Dropout Operation:** Allows 100% duty cycle for low input-output differentials.  
- **Internal Soft-Start:** Limits inrush current during startup.  
- **Short-Circuit Protection:** Enhances reliability under fault conditions.  
- **Low Quiescent Current:** 100µA in shutdown mode.  
- **Thermal Shutdown:** Protects the device from overheating.  

This regulator is suitable for applications such as industrial power supplies, automotive systems, and battery-powered devices.
