Description and Introduction

High Efficiency Step-Down Switching Regulator Controllers The LTC1147CN8-3.3 is a synchronous step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** Fixed 3.3V  
- **Input Voltage Range:** 4V to 14V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 90%  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Regulation Type:** Synchronous Buck (Step-Down)  

### **Descriptions and Features:**  
- **High Efficiency:** Uses synchronous rectification for improved efficiency.  
- **Low Quiescent Current:** Typically 1.5mA in operation.  
- **Burst Mode Operation:** Reduces power consumption at light loads.  
- **Short-Circuit Protection:** Includes current limiting and thermal shutdown.  
- **Fixed Output Voltage:** No external feedback resistors needed for 3.3V output.  
- **Minimal External Components:** Requires only an inductor, capacitors, and a diode for basic operation.  

This regulator is designed for applications requiring a compact, efficient step-down converter with a fixed 3.3V output.
