Description and Introduction

1.2A, High Efficiency Step-Down DC/DC Converter The LTC1265CS-3.3#PBF is a switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 1A  
- **Input Voltage Range:** 4V to 12V  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Lead SOIC  
- **Topology:** Step-down (buck) synchronous regulator  
- **Low Dropout Operation:** Yes  
- **Quiescent Current:** 1.5mA (typical)  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions:**  
The LTC1265CS-3.3#PBF is a high-efficiency, synchronous step-down DC/DC converter designed to deliver a fixed 3.3V output from an input voltage range of 4V to 12V. It integrates both power switches, reducing external component count and simplifying design.  

### **Features:**  
- Synchronous rectification for high efficiency  
- Low dropout operation  
- No Schottky diode required  
- Adjustable switching frequency (via external resistor)  
- Soft-start capability  
- Short-circuit and thermal protection  
- Compact 16-lead SOIC package  

This regulator is suitable for applications requiring efficient power conversion in space-constrained designs.
