Description and Introduction

Synchronous Regulator Controller for N- or P-Channel MOSFETs The LTC1266AIS is a high-efficiency, synchronous step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Input Voltage Range:** 4V to 24V  
- **Output Voltage Range:** 1.25V to 20V (adjustable)  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions and Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Current Mode Control:** Ensures stable operation with fast transient response.  
- **Low Dropout Operation:** Allows the output to remain regulated even when the input voltage is close to the output voltage.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Short-Circuit Protection:** Enhances reliability under fault conditions.  
- **Low Quiescent Current:** 1.5mA typical when operating, 10µA in shutdown mode.  
- **Thermal Shutdown:** Protects the device from overheating.  

The LTC1266AIS is designed for applications requiring high efficiency and compact power solutions, such as portable devices, telecom systems, and industrial equipment.
