Description and Introduction

Dual High Efficiency Synchronous Step-Down Switching Regulators The LTC1267CG is a high-efficiency, synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** 2.85V to 15V (adjustable)  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**  
- The LTC1267CG is a synchronous buck regulator designed for high efficiency and compact power supply solutions.  
- It features a fixed-frequency PWM architecture for stable operation.  
- Includes internal power MOSFETs for reduced external component count.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Low Dropout Operation:** Allows the output to stay regulated even when the input voltage is close to the output.  
- **Short-Circuit Protection:** Safeguards against output faults.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Adjustable Output:** Set via an external resistor divider.  
- **Thermal Shutdown:** Protects the device from overheating.  

This information is based solely on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
